Abstract
A simple method for enriching conventional homogenized porous plasticity models with size-dependence for micron scale voids is proposed. A recent strain gradient plasticity theory with dissipative gradient effects is generalized to finite strains in order to quantify size-scale effects on void growth under different loading conditions. Based on numerical cell model studies for regularly distributed voids, the size-dependence of homogenized yield...
