| Abstract: | The present work aims at studying numerically the influence of void concentration, number of voids and absence/presence of inclusion on void collapse/growth and coalescence in materials submitted to shear loading. Starting from the experimental observation that voiding mostly forms within bands of localised deformation in the form of void sheets, the geometrical configuration retained to that purpose is a layer of periodic cells with 1–5, empty or particle-containing voids, subject to simple shearing. |
