Abstract

The mechanical response of cross-ply SiC/CAS ceramic matrix composites was investigated experimentally and analytically. The experiments consisted of recording stress-strain behavior, counting matrix cracks and measuring the interlaminar shearing strength. The analysis employed an extended shear-lag model which incorporated non-linear behavior of the 0° plies and interlaminar slip between the 0 and 90° plies. The evolution of the multi-cracking process was determined by means of fracture criterion, leading to the prediction of the overall stress-strain response of the cross-ply laminate.
