The microcracking behaviors of two-phase materials with microinclusions exhibiting transformation plasticity are analyzed by using the two-dimensional meso-analysis method. Numerical studies have been conducted for some aspects of transformation-induced plasticity which is observed in Zirconia toughened ceramics. Irreversible strains and macro, stress-strain relationship due to dilatational transformation have been simulated under tensile loading condition. R-curve behaviors and microcracking patterns considering the mismatch between matrix and inclusions and the transformation plasticity of second-phase particles have been discussed under model-I loading condition. Influences of the total area fraction and the size of second-phase particles have also been studied through the calculated results.
