This paper presents on the cracking mechanisms of fiber-eutectics and transformation particles composite ceramic. First, supposing that the tensile stress among fiber eutectics is transmitted by means of shear stress along the interfaces of fiber eutectics, based on fiber eutectics having lengths smaller than the critical length, the force acting along the fiber eutectic can be determined by the shear stress. Then, the probability of ending fiber eutectics and bridging fiber eutectics can be gotten by defining a critical district. Finally, according to the random orientations and the lengths of the fiber eutectics, composite ceramics will crack by slip incompatibility among bridging fiber eutectics. The cracking stress of the composite ceramics is built.
