摘要
Abstract
An exponential multi-layered interfacial zone model was developed for the solid propellant/liner interface crack. In the model, the interfacial zone was divided into some sub-layers with the initial modulus of each sub-layer varying in an exponential manner. The method of Fourier transform was employed and a set of Cauchy singular integral equations was derived. A collocation method was used to obtain the semi-analytical solution of the crack problem under plane stress condition, and the influences of the interfacial zones parameters on the stress intensity factors were discussed when the crack was subjected to normal and shear stresses. The results show that when the interfacial zones modulus decreases, the absolute values of the stress intensity factors decrease significantly. The effects of the interfacial zones thickness on the stress intensity factors are not significant relatively.关键词
