Abstract

This work addresses the computational aspect of a model for ductile damage at finite strains. Elasto-visco-plastic model including non-linear (time dependent) isotropic and kinematic hardening is extended with isotropic damage. The constitutive equations are numerically integrated using algorithm based on operator split methodology (elastic predictor visco-plastic corrector). The Newton-Raphson method is used to solve the discretized evolution equations in the visco-plastic corrector stage. The finite element method is used in the approximation of the incremental equilibrium problem and the resulting equations are solved by the standard Newton-Raphson procedure.
