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 Laplacian thereof. The gradient terms in yield criterion
show an important role on modelling strain-softening phenomena of material. The influence of the mesh
size on the elastic-plastic deformation behavior and the effect of the characteristic length parameter for
localization prediction are also investigated. The proposed nonlocal plasticity shows that the load-strain
curves converge to one curve. Results using nonlocal plasticity also exhibit much less sensitivity than
those for a corresponding local plasticity formulation.
