%X The yield criterion for porous materials during rolling is proposed based on the concept of "the materials begin to yield when the apparent strain energy approaches to a critical value" . The relationships between thickness strain and relative density, thickness strain and longitudinal strain, plastic Poisson ratio and relative density, relative density and thickness stress during rolling are derived according to the mass conservation law. The theoretical predictions show a good agreement with the experimental results of FVS0812 heat resistant porous aluminium alloy prepared by spray deposition technology.
