摘要
本文分析位于两个拼接的半无限各向同性弹性体界面上的运动Ｇｒｉｆｉｔｈ裂纹的应力强度因子．所研究的问题通过采用Ｇａｌｉｌｅａｎ和Ｆｏｕｒｉｅｒ变换转化为一组联立的对偶积分方程组，再将之转化为求解一组联立的奇异积分方程组。
This paper is concerned with the stress intensity factor of a Griffith crack moving along the interface of two bonded isotropic elastic half planes. The analysis employs successive application of Galilean and Fourier transformations to lead to a set of simultaneous dual integral equations which can be further reduced to a system of algebraic equations by using Jacobi polynomials.
