Summary
The theoretical developments and the numerical applications of a time-dependent damage law are presented. This law is deduced from considerations at the micro-scale where non-planar growth of micro-cracks, following a subcritical propagation criterion, is assumed. The passage from micro-scale to macro-scale is done through an asymptotic homogenization approach. Results of numerical simulations of time-dependent damage behavior are presented.
