Most failures of ductile materials in metal forming processes occurred due to material damage evolution - void nucleation, growth and coalescence. In this paper, the modified yield function of Liao et al in conjunction with the Hosford`s yield criter

Most failures of ductile materials in metal-forming processes occur due to material damage evolution (void nucleation, growth, and coalescence). The current article examines the modified yield function of Liao et al., in conjunction with Hosford’s

In this paper, the strain localization of voided ductile material has been analyzed by nonlocal plasticity formulation in which the yield strength not only depends on an equivalent plastic strain measure (hardening parameter), but also on the Laplaci
