摘要
本文用Laplace变换、Wiener-Hopf和Cagniard-de Hoop方法求解了各向异性介质中一半无限长Ⅲ型裂纹突然以匀速扩展的问题.给出了瞬态的位移场和运动裂纹尖端的动态应力强度因子.
The Laplace transform, Wiener-Hopf technique and Cagniard-de Hoop method are used to solve the problem of a mode Ⅲ semi-infinite crack which propagates suddenly at constant velosity in an anisotropic medium. The transient displacement field and the dynamic stress intensity factor at the moving crack tip are obtained.
