Monte Carlo Simulation on the Matrix Failure Considering the Interfacial Debonding Energy

摘要：

　　Considering the interfacial debonding energy at the fiber/matrix interface,an improved Monte Carlo simulation has been done on the matrix failure of the unidirectional ceramic matrix composites.Firstly,the debond length formula was given,then the stress/strain formula was also reviewed,and the matrix failure was simulated by the improved Monte Carlo model,the effect of the interfacial debonding stress on the matrix cracks evolution and the stress/strain curve was considered especially.Lastly,the result was compared to the experiment data.The result shows that the larger interfacial debonding energy at the fiber/matrix interface,the larger debond stress,the crack density increase more slowly,the mean crack density smaller,the final failure strength lower.The improved Monte Carlo simulation result is agreed well with the experiment data.
