Micropolar hyper-elastoplasticity: constitutive model, consistent linearization, and simulation of 3D scale effects

SUMMARY A computational model for micropolar hyperelastic‐based finite elastoplasticity that incorporates isotropic hardening is developed. The basic concepts of the non‐linear micropolar kinematic framework are reviewed, and a thermodynamically consistent constitutive model that features Neo‐Hooke‐...
