The finite element computational results are used to evaluate the accuracy of the use of the anisotropic Gurson yield criterion to model the macroscopic plastic behavior of porous materials. First, we...

... is considered. We also discuss issues of connectivity at the scale of the porous material rather than element-by-element. This work points toward use of simple constructions to model complex behavior, and may ultimately provide insight into modeling of a large class of porous materials. [S0094-4289(00)01604-2...
