摘要：考虑了无界弹性体中半平面裂纹的动应力强度因子历史，裂纹面受一对沿垂直于裂纹边缘方向移动的点载荷组成的牵引分布。通过推广Freund最近提出的方法，得到了裂纹边缘沿着任意点的Ⅰ型应力强度因子随时间变化的精确表达式。求解方法是基于积分变换法和复变解析函数理论。一些功能的解决方案进行了讨论，并提出了各种点负载速度的图形结果。
Abstract : The dynamic stress intensity factor history for a half plane crack in an otherwise unbounded elastic body, with the crack faces subjected to a traction distribution consisting of a pair of point loads that move in a direction perpendicular to the crack edge, is considered. The exact expression for the mode I stress intensity factor as a function of time for any point along the crack edge is obtained by extending a procedure recently introduced by Freund. The method of solution is based on integral transforms methods and the theory of analytic functions of a complex variable. Some features of the solution are discussed and graphical results for various point load speeds are presented.
