Abstract A zero-order model is presented, which allows calculation of the stress distribution in porous epoxies by taking into account the interaction between randomly distributed voids. These results demonstrate that the mean value of the stress concentration factor increases with the volume fraction of voids. This leads to a decrease in sample yield strength. However, the generation of a porous morphology also creates a considerable number of regions where the stress is completely released. The theoretical predictions are in good agreement with experimental results obtained with macroporous epoxies, which were prepared based on the chemically induced phase separation technique, and tested under uniaxial compression.
