引言动态应力强度因子的计算已经成为很重要的研究课题。这对于研究裂纹在动荷下的扩展及判断结构的可靠性方面均具有重要的实际意义。边界元法一直是计算断裂力学领域中得到广泛应用的方面之一。对于静态的断裂力学问题,它已经做出了十分突出的贡献。目前与时间相关的实际问题的研究已广泛开展起来了。用边界元法研究动
Introduction The calculation of dynamic stress intensity factor has become a very important research topic. This is of great practical significance for studying the crack propagation under the dynamic load and the reliability of the structure. Boundary element method has been one of the most widely used fields in the field of fracture mechanics. It has made a very prominent contribution to the problem of static fracture mechanics. The current study of practical issues related to time has now been extensively conducted. Using Boundary Element Method to Study Activity
