本文用Fourier变换和Wiener-Hopf方法研究了在SH波的作用下各向异性介质中匀速扩展裂缝问题,求出了问题的位移场的积分表达式并给出了动态应力强度因子的封闭解。
In this paper, the Fourier transform and Wiener-Hopf method are used to study the problem of uniform expansion of cracks in anisotropic media under the action of SH waves. The integral expressions of the displacement field of the problem are obtained and closed solutions of dynamic stress intensity factors are given.
