Failure of structures usually starts from the initial diffuse damage and ends eventually with the localized rupture. During the last half century, many theoretical models have been proposed to characterize material behavior with softening regimes. Meanwhile, various computational approaches have also been presented. 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 still need to be developed. The purpose of this minisymposium is to stimulate an exchange of ideas among researchers working on the computational failure mechanics of solids and structures, including but not limited to, the following approaches:

1) discrete crack approaches such as zero-thickness interface elements, enriched finite element method with nodal or elemental enrichments;
2) smeared crack approaches such as isotropic and anisotropic damage models, plasticity, or combined plastic-damage models;
3) regularized crack approaches such as phase-field models, thick level-set method, variational approaches to damage and fracture, nonlocal and gradient-enhanced models;
4) combined continuous and discontinuous approaches that characterize the entire failure process from the initial diffuse stage to fully localized failure.
