摘　　要：三维裂纹在动态断裂力学中,由于其数学和物理上的复杂性,求解其动态应力强度因子受到一定的约束。文中主要介绍了利用有限元分析软件ANSYS来求解三维动态应力强度因子。Because of the complexity in mathematics and the physics, it is certainly limited to solve the three-dimensional dynamic stress intensity factors. The application of the ANSYS software in solving the three-dimensional dynamic intensity factors is introduced.

关 键 词：动态应力强度因子 三维裂纹扩展 有限元
