摘要：An iterative method was presented for simulation of the failure process of SiC/SiC mini-composites with pyrolytic carbon interphase exposed to air oxidizing environments under a constant load at 900 degrees C. This method was based on the possibility fracture strength of SiC fibers caused by random defects and the fiber stress distribution in mini-composites. The fiber strength probability model and Monte Carlo simulation were combined to generate the fracture strength along SiC fibers at 900 degrees C. The influence of fiber arrangement on fiber stress distribution was assessed to simplify the geometry model which was used to calculate the fiber stress distribution in the mini-composites. The failure process of the mini-composites was simulated, and the calculated oxidation life of the mini-composites matches the experimental data well with an error of -9.40%.
