本文考虑了无限弹性体中半平面的动应力强度因子历史，裂纹面受两对沿垂直于裂纹边缘方向移动的复合型点载荷组成的牵引分布。该方法的解决方案是基于应用积分变换与维纳霍普夫技术和Cagniard-de Hoop方法
The dynamic stress intensity factor history for a half plane in an otherwise unbounded elastic body, with the crack faces subjected to a traction distribution consisting of two pairs of combined mode point loads that move in direction perpendicular to the crack edge is considered. The method of solution is based on the application of integral transform together with the Wiener Hopf technique and the Cagniard-de Hoop method
