Abstract

This study considers extension of the distributed-element model to account for the deformation-induced anisotropy demonstrated in subsequent yield surfaces. By modifying the shape parameter of the strength-distribution function in the model as a function of the accumulated plastic deformation and the preloading direction, the DEM is able to account appropriately for major features of the subsequent yield surfaces demonstrated by real materials under proportional loading. The proposed modeling technique is confirmed by performing numerical simulations and comparing with experimental results available in the literature.
