...–Tvergaard’s yield function ( Tvergaard, V., 1981, Int. J. Fract., 17, pp. 389–407 ) and its associated flow rule for voided solids. The effects of hardening and evolution of void shape on void growth are considered. Various fracture criteria are employed to predict the process conditions at which central...
