| 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. |
