Abstract Constitutive equations of finite strain elasto-plasticity are coupled to continuum damage mechanics simulate the initiation and propagation cracks in ductile materials. The diffuse deterioration material’s strength is modelled using porosity as a parameter. We show that local model yields simulation results, pathologically dependent on FEM mesh upon refinement: (i) structural behaviour...

Numerical models of deformation, damage and fracture in particle-reinforced composite materials, based on the method of multiphase ®nite elements (MPFE) and element elimination technique (EET), are presented in this paper. The applicability of these techniques for di€erent materials and di€erent levels of simulation was studied. The simulation of damage and crack growth was conducted for severa...

Abstract This study presents a gradient damage model for ductile fracture, in which the hardening modulus is degraded by accumulation of plastic deformation and volume expansion caused negative hydrostatic pressure. The proposed fulfills thermodynamic requirements, governing equations are derived from energy minimization principles. Two parameter studies carried out to confirm basic performance...
