In this study, we have reviewed recently published strength-porosity data of porous
ceramics, and compared these data with those computed from both the minimum contact solid area
(MCA) and the pore stress concentration effect (SCE) models. We observed that the theoretical data
(MCA model) matched better the experimental results of ceramics in the low volume fraction porosity
range (P < 0.25) range, whereas in the volume fraction porosity range (P > 0.25), the SCE model better
predicts the experimental results.
