||Recently there has been a renewed interest in the development of novel computational approaches for modeling damage phenomena in materials with high fidelity. Damage phenomena such as crack nucleation/propagation, ductile damage, fatigue and fracture have been researched using a new class of physics-based models which make use of high performance computational frameworks. Most of these damage phenomena are multi-scale in nature (spanning several orders of time and length scales), and occur as a result of multiple interactions between the host material and applied loading or service conditions. For example, crack propagation depends strongly on the host material (crystal structure), pre-existing defects, microstructure, and interaction of these features in response to macroscopic loads.
Various computational techniques have gained popularity or have emerged during the past two decades, ranging from contimuum approaches that includes variations of extended finite element methods (XFEM), cohesive zone method (CZM), peridynamics, and meshless methods, to mesoscale and atomistic paradigms with phase-field models for fracture, crystal plasticity dislocation dynamics, or atomistics frameworks quasi-continuum and atomistic-continuum modeling approaches. These methods make use of new understanding of materials behavior and/or advancements in computational approaches and attempt to provide alternative high-fidelity approaches for modeling.
This symposium aims to gather researchers at the intersection of computational/applied mechanics, materials science, multi-scale modeling, and numerical techniques to discuss the state-of-the-art, challenges, and research trends in the modeling of damage phenomena in materials. The symposium will provide a forum for researchers across the community to exchange ideas and accelerate the development and advancement of these emerging damage modeling techniques.
Topics of interest include (but not limited to):
1. Recent advancements in XFEM, CZM, and related techniques
2. Multiscale mechanics and multiphysics aspects of damage modeling
3. Crack propagation and fracture modeling using peridynamics and phase-field methods
4. Meshless methods and recent trends in hybrid formulations for extreme deformation scenarios
5. Novel approaches for coupling damage behavior at different time and length scales. Scale-bridging and parameter estimation approaches.
6. Physical/experimental underpinning of material models and determination of model parameters.
7. Recent advances in discrete dislocation dynamics simulations and incorporating for dislocation interactions with interfaces (e.g. grain boundaries and twin boundaries)
8. Computational/algorithmic aspects and benchmark studies on high-fidelity simulation of damage from nano-to-macroscale; interaction of damage with microstructure.
9. Quantification of uncertainties in damage prediction; verification and validation studies
Due to the potential interdisciplinary nature of research under this theme, studies involving theoretical/computational/applied research are welcome. Multiscale/multiphysics aspects of damage modeling in scenarios like: environment assisted cracking, failure of additively manufactured components, thermo-mechanical failure, diffusion induced fracture, mechanically driven microstructure evolution, and materials processing are of special interest. Collaborative efforts involving simulation and experiments are also encouraged.
