Advanced local and nonlocal multiphysics modelling of damage behavior coupling

When subjected to various loading paths, materials may exhibit severe strain localization leading to the occurrence of different kinds of damage. This damage occurrence influences strongly the material behavior including different involved physical phenomena. This mini-symposium is dedicated to the formulation and implementation of various advanced constitutive equations describing the strong and full coupling between damage and other associated physical phenomena (inelastic flow, hardenings, anisotropies, textures, heat fluxes, diffusion, corrosion, healing …).

Typical topics of interest concern the formulations involving strong coupling between damage and other physical phenomena exhibited by material behavior. Classical local formulations as well as advanced nonlocal formulations in the framework of generalized continua (higher gradient continua, fully nonlocal continua, phase field theories…) are also of interest.

Experimental, theoretical and numerical works are welcomed with applications to different types of materials.

Damage modelling of engineering structures: from localized cracking to structural collapse

Starting with localized cracking and ending with structural collapse, the progressive failure of engineering structures is usually governed by damage evolution in different levels. To this end, theoretical models and numerical methods for predicting the damage behaviour of structures play increasingly important roles in the design of structures, although their current status lag far behind engineering practices. This symposium aims to promote collaborations among academic researchers and industrial engineers in developing and applying damage models and related numerical methods to the prediction of nonlinear behaviour of engineering structures. Those who have been working on related fields are cordially invited to exchange their ideas and research outcome in this mini-symposium.

Model-Based Simulation of Damage Responses to Extreme Loading Conditions

Damage responses to extreme loading conditions (high loading rate, high pressure and high temperature) occur in many areas of modern engineering applications such as impact, penetration, explosion, high-speed machining, additive manufacturing and aerospace engineering. The multiscale complexity involved in damage responses imposes grand challenges to analytical, experimental and numerical investigations. To better predict the onset and evolution of localized damage, fracture, fragmentation and phase transformation, the multiscale and multiphysics mechanisms involved in damage responses must be fully understood, and new theories and numerical methods remain to be developed with improved fidelity and reduced assumptions. This mini-symposium aims at providing an international forum for academic researchers and industrial engineers working on the related analytical, experimental and computational topics to discuss the recent progress, to promote collaboration, and to identify the challenging research and development issues and the future direction to proceed.

Computational modeling of damage and failure in solids and structures

Failure of structures usually starts from the initial diffuse damage and ends with the eventual localized rupture. During the last half century, a large volume of theoretical models has been proposed to characterize material behavior with softening regimes. Meanwhile, various computational approaches have also been developed. However, despite the recent noteworthy contributions, physically sound and mathematically well-posed models and methods for the description of the entire failure process in solids and structures are still insufficient. The purpose of this mini-symposium is to stimulate an exchange of ideas among researchers working on the computational fracture/failure mechanics of solids and structures, including but not limited to, the following approaches:

• Discrete crack approaches such as zero-thickness interface elements, enriched finite element method with nodal (XFEM/GFEM) or elemental enrichments (E-FEM);
• Smeared crack approaches implemented in novel numerical contexts, e.g., mixed finite elements, mesh-free method, discontinuous Galerkin method, isogeometric analysis, virtual elements, scaled boundary finite elements, etc.;
• Regularized crack approaches such as phase-field models, thick level-set method, variational approaches to damage and fracture, nonlocal and gradient-enhanced models, and peridynamic models;
• Combined continuous and discontinuous approaches that characterize the entire failure process from the initial diffuse stage to the final fully localized failure;
• Static and dynamic fracture; brittle and ductile fracture; shock, impact and fragmentation;
• Multi-scale and stochastic analysis of fracture such as computational homogenization (FE²), bridging domain method, etc.
• Experimental validation of numerical methods for damage and fracture; inverse analysis and model calibration.

Failures and Damages in Composite Materials and Structures

Damages and failures of composite materials and structures are among the most challenging topics in solid mechanics. Extensive cost both in money and in time has to be spent to understand failure behaviors of a composite structure in the current practice. Traditional approaches to them are phenomenological, without any knowledge of internal stresses of the constituent fiber and matrix in the composite. Many important issues in the analysis of composite failures, however, cannot be well addressed without a micromechanics approach to the internal stresses. Examples include a crack occurring on the fiber and matrix interface, thermal residual stresses, plastic behaviours of the composite, etc. Multi-scale modelling to composite failures has become popular in the current literature. With it, one of the most challenging issues is in how to define the critical strength/ failure data of the constituents especially of the matrix necessary for detecting a composite failure. Experiments can measure only the original critical parameters of the monolithic matrix, with which a predicted failure behavior of the composite may be far away from a reality. Some latest reports show that the homogenized stresses of the matrix must be converted into true values in order that a composite failure can be detected against the original critical parameters of the matrix. Moreover, characterization of various composite failures, e.g., initiation of laminate delamination, debonding of the fiber and matrix interface, and in-situ damage information under an impact, still attract many people’s attention. This mini-symposium provides a platform for the people working in composite failure and strength area world-widely to exchange their findings, concepts, and methodologies.

Damage Diagnosis and Condition Assessment of Historical Buildings

Historical buildings represent an important portion of the World Cultural Heritage and need to be conserved and maintained. The protection of historical buildings against structural risks is usually a difficult task, which involves the analysis and assessment of the building in its present state, studies on damage detection methods and researches on the identification of the likely causes of present damage and so on. Nevertheless uncertainty regarding the mechanical properties of the materials involved, their highly nonlinear behavior, the possible lack of effective connections among the structural elements and the presence of different materials (wood, stone, mortar and iron), make the analysis of the response of the entire structure to generic loads extremely complicated. In recent years, non-destructive testing (NDT) methods were developed and used as tools to provide non-invasive condition diagnostics, as well as some damage identification methods based on static or/and dynamic responses. Condition assessment methods based on analytical, numerical and experimental analysis have been also developed to evaluate the structural state of historical buildings. The scope of the mini-Symposium mainly focus on the issues of damage diagnosis and condition assessment of historical buildings as follows:

• Survey techniques
• Non-destructive testing, inspection, and monitoring
• Experimental results and laboratory testing
• Analytical and numerical approaches
• Seismic behavior and retrofitting
• Detailed and state-of-the-art case studies, including truly novel developments

Damage of engineering materials under multi-field loadings

The Symposium will focus on various aspects of mechanical behaviour and damage evolution of engineering materials under multi-field loadings, including electronic materials under the coupled thermal-electrical-mechanical loading to induce the resistance deterioration against fatigue and creep in the semiconductor industry; steel and concrete under the fire-earthquake coupled loading to induce extreme disasters such as progressive collapse in the civil engineering; biomaterials on the areas of stem cell biology; tissue repair and regenerative medicine under the mechanical-biological coupled loading in the biomechanics and biomedical engineering. Regarding the complicated loading scenarios, the interactions of different deformation and damage responses corresponding to all sorts of loadings are extremely challenging. Despite the significant distinctions between various materials, the newly developed approaches to reveal the dominant mechanism are highly deserved to be exposed and emphasized in other science and engineering disciplines. The scope of the Symposium is to discuss the theoretical and experimental approaches to reveal the underlying mechanism of multi-field loadings in different disciplines to inspire interesting ideas and potential applications of engineering materials under complicated working scenarios.

Damage of Composites under Impact Loadings

Over the past several decades, composite structures have found increased usage in many industries including the aerospace, automotive, civil, marine, and sports. Impact failure of composite structures can reduce significantly the resultant strength and result in catastrophic consequences and loss of property. To enable reduced weight, increased performance, and affordable composite materials and structures, a large number of experimental, theoretical and computational studies have been conducted to explore the impact failure mechanism. Due to the complicated failure behavior of composites and the destructive nature of impact events, the damage/failure mechanism and associated predictive modeling approach for composites and its structures remains a significant challenge.

This mini-symposium aims to bring together researchers and engineers working on impact failure of composite structures using all types of approaches. It seeks to synthesize recent advances in experimental techniques, mathematical models and computational methods/algorithms, as well as for designing impact resistant structures/systems. Research and industrial applications addressing all aspects of responses of composite matrix, fiber filaments, interface, fabrics, laminates, and textile composites et al. are welcomed. Numerical modelling and simulation efforts with experimental validation/verification are particularly encouraged.

Short crack behavior and its application

The propagation of short crack is very important in most fatigue design applications because the uncracked structural components frequently spend most of their lives on it. Moreover, it is impossible to guarantee that structural components are really free of small cracks during their service lives, or even in the process of their manufacture. The understanding of the short crack behavior can help to guarantee the reliability of mechanical design and structural integrity evaluations. However, the traditional LEFM assumption will be violated if these mechanically short cracks are small in comparison to the plastic zone near the crack tip. Plenty of methods, such as the modified LEFM, the elastic-plastic fracture mechanics (EPFM) or the crack opening displacement (COD), are available to characterize the short crack behavior.

The topics of the Symposium include, but are not limited to, the following:

• Behavior of short cracks;
• Damage-tolerant design;
• Non-propagating short cracks;
• Stress concentration or notch sensitivity;
• Characterization of crack tip;
• Initiation fatigue life prediction.

The materials of interest range from traditional ones such as metals, alloys, ceramics, polymers and composites to advanced and emerging materials as well as bio- and biomedical materials.

Thermodynamics Based Modelling of Damage Evolution, Fatigue Life and Failure

Damage evolution, fatigue life and failure has historically been modeled by curve fitting phenomenological models. This mini-symposium will cover research efforts proposing damage evolution models based on fundamentals of physics, thermodynamics and Mechano-thermodyamics. Mathematical derivation, and mathematical proof of these models as well as their experimental verifications will be presented.

Using The Unified Theory of Newtonian Mechanics and Thermodynamics for damage mechanics is one of the hottest topics in this field. In the unified theory entropy generation under multiple loading mechanisms, i.e. Thermal, mechanical, electrical, chemical, corrosion, radiation, and etc. is used for evolution of degradation in solids and interfaces. Since mathematical proof of this theory in 2016 by Sosonovskiy and Sherbakov, it has received great research interest.

The symposium will cover new theoretical models and experimental verifications of physics based models.

Life-cycle based study and design of concrete-filled steel tubular structures

As an efficient composite structural form, concrete-filled steel tubular (CFST) structures have been widely used as major structural components in large-scale infrastructures and structures in China and around the world, such as high-rise building, bridges and airports, etc. Due to its unique structural form, a wide range of constructional, mechanical and environmental factors may influence its performance during its life-cycle, such as residual stress and preload on the steel tube, long-term loading effects of concrete, corrosion of the steel tube, and the coupling effects of different hazard actions. Thus, the analysis and design of CFST structures should be carried out based on a life-cycle prospect with all these different factors considered. This mini-Symposium concentrates on the recent developments on the life-cycle based study and design of CFST structures, which may include the damage and failure of CFST structures subjected to possible hazard loads during the full life-cycle and their combined effects, the performance of CFST structures incorporating the construction process, long-term effects and the environmental effects. It also concerns the establishment of future design principles and methodologies for CFST structures based on the full life-cycle analysis philosophy.

Numerical Advances in Multiscale Failure Analysis in Geo-Engineering

Geomaterials such as soils and rocks are heterogeneous media consists of complex microstructures, whose macro-behaviors and failure process are heavily related to their microstructures evolution. Many recent research works concerning soil and rock are focused on the multiscale character of these materials and related engineering aspects. The multiscale approach makes it possible to link the microscopic features of the material (microstructure, microphysics, microscopic properties) with the behaviour observable and measurable at the macroscopic scale. By providing the “bridge” between the scales, the modelling becomes more predictive and efficient. During the last decades, significant advances have been achieved on multiscale approaches in geomechanics, on experimental investigation, theoretical development and numerical modeling. This mini-symposium aims at bringing together engineers, mechanical and computational researchers to discuss and exchange ideas on up-to-date developments and advances on various aspects of multiscale approaches in geomechanics. Without to be exhaustive, the following topics will be covered in this session:

• Advanced experimental techniques for investigating deformation and failure behaviors in heterogeneous geomaterials
• From micro-structural evolutions to macroscopic behaviors
• Nonlinear and linear homogenization techniques for elasticity, plasticity and damage
• Advanced numerical methods for full field simulations of heterogeneous geomaterials (elastic deformation, plastic deformation, cracking, etc.)
• Multiscale modeling of cracking and failure process in structural scale (extended finite element methods, phase field methods, discrete element method etc.)
• Time-dependent deformation and failure with microstructural evolutions
• Multiscale approaches for THM-C coupling problems
• Engineering applications and case studies

Damage mechanics for rock mass

Rock mass is a natural damage material since it is porous medium with joints and fractures. The propagation and coalescence of crack would affect properties of rock mass significantly. So it is important to study the process of crack and failure, and evaluate the stability of rock mass engineering, such as dam foundations, slopes and tunnels.

Damage mechanics for rock mass is a widely used method in stability analysis of rock mass structures. The current research interest about rock damage mainly focus on the thermodynamic basis theory, experiments, damage model and numerical simulation. The scope of this Mini- Symposium include theoretical model, numerical simulation, experiments and engineering applications about rock mass.
