Abstract
A lower bound approach is proposed for the first time to solve the macroscopic yield loci of porous materials. The results are then compared with Gurson's upper bound yield loci and those of the experiments. It is shown that the present analysis is much more in accordance with the experimental results than the Gurson's.
