Abstract:The effect of residual stresses on strength of carbon fiber-reinforced ceramic composite was theoretically analysed and simulated by means of XFEM (extended finite element method) with commercial software, ABAQUS. Theoretical analysis indicated that the crack evolution was influenced by the residual stresses existing in the ceramic composites and the fracture strength of the ceramic composites would be increased when the compressive stresses occurred in the matrix. Uniaxial tensile simulation revealed that the final failure strength of ceramic composite was improved by ~8% in comparison with monolithic ceramic. The simulated results of the stress state of each component in the ceramic composites were in well accordance with the theoretical ones. © 2017 International Committee on Composite Materials.
