Mitigation of spall fracture by evolving porosity
TLDR
In this article , the authors report on finite deformation finite element calculations that analyze the response of porous ductile materials subjected to impact loading conditions and show that porosity in ductile material can, under certain circumstances, mitigate spall fracture by attenuating stress waves.About:

Influence of voids on shear band instabilities under plane strain conditions
TL;DR: In this paper, the effect of microscopic voids on the failure mechanism of a ductile material is investigated by considering an elastic-plastic medium containing a boubly periodic array of circular cylindrical voids.
