The need for modeling damage and fracture growth under combined mechanical and multiphysical loading conditions has become more common for applications involving both natural solids and engineered products. This mini-symposium aims to provide a platform to discuss the recent advancements in computational fracture modeling within multiphysics loading conditions. The topics of interest include, but are not limited to the following:
・Novel discretization techniques, e.g. phase-field and regularized damage models, extended/generalized finite element methods, cohesive zone methods, meshless and particle methods, peridynamics.
・Constitutive and phenomenological modeling of fracture initiation and propagation, with multiphysics considerations
・Mixed finite element formulations and stabilization techniques
・Spatial and temporal multiscale techniques to represent various physical processes across scales
・Computational homogenization and reduced-order modeling
・Numerical solution algorithms aimed to reduce the computational cost of non-linear multiphysics problems, including: staggered solution methods, and iterative methods
・Methods that characterize the onset of failure localization, including stability analysis, perturbation techniques, acoustic tensors, and eigenvalue problems
・Example applications areas: fluid-structure interaction, hydraulic fracture, thermo-plasticity, electro- and chemo-mechanical couplings, corrosion and other environmental factors, rupture of soft materials.
