Plasticity Modeling and Computation

Rate-independent elastoplasticity; classical plasticity models for metals and cohesive-frictional materials; cap plasticity models for porous materials; return-mapping algorithm; shear bands, faults, and other discontinuities; Lagrange multipliers, penalty, and augmented Lagrangian methods for frictional contact; extended finite element and strong discontinuity methods; rate-dependent viscoplasticity; Duvaut-Lions and Perzyna models; creep and stress relaxation.
