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
Non-linear laws of fluid flow through anisotropic porous media are written out in invariant tensor form for all crystallographic point symmetry groups. The equations, as is customary in seepage theory [1,2], are represented by expressions containing the seepage velocity up to and including the third
## 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
