The attached, to appear in I.J. Impact Engng., is an attempt to simplify such very complex calculations using an incubation time concept for defects coalescence, in the spirit of Tuler and Butcher and others.
By comparing the calculations and the experiments, it seems that the approach works nicely, produces realistic results, and most of all does not necessitate complex models with too many parameters of very sophisticated FE formulations.
Enjoy
