This study investigates the mechanical behaviour modelling of IN100 cylinder when subjected to cyclic loading. To predict damage, a variational approach of phase field damage is coupled with plastic deformation. Numerical simulations were conducted using Comsol Multiphysics finite element software. Numerical results of the considered test assess the coupling behavior of damage accumulation and plastic deformation which leads to capture a realistic behaviour of the structure. Also, these findings proved the impact of the isotropic and kinematic hardening on the model response by considering the material history-dependent behavior.

摘要

This study investigates the mechanical behaviour modelling of IN100 cylinder when subjected to cyclic loading. To predict damage, a variational approach of phase field damage is coupled with plastic deformation. Numerical simulations were conducted using Comsol Multiphysics finite element software. Numerical results of the considered test assess the coupling behavior of damage accumulation and plastic deformation which leads to capture a realistic behaviour of the structure. Also, these findings proved the impact of the isotropic and kinematic hardening on the model response by considering the material history-dependent behavior.
