## Abstract A plasticity theory for porous metals is proposed. A simple model of a porous materials is analysed by the finite element method. Small strain elasticβplastic analysis provides stressβstrain curves, yield stressed and incremental plastic strain vectors for different void ratios. An asse
plasticity theory for sintered porous metals with anisotropic pore structure is proposed. It is assumed that anisotropy of the bulk material and its symmetry group is generated by the pore structure that is described by the structural permeability second-order tensor. In the first part the developme
