摘要
运用ANSYS商用有限元软件,采用非奇异单元和Newmark积分算法,通过最小二乘法拟合,准确地获得了多个模型动态应力强度因子的解。所使用的方法适用范围广,这对于运用线弹性断裂动力学解决工程中的实际问题是有益的和必要的。
Solutions to dynamic stress intensity factor of several models were obtained accurately, using ANSYS commercial FEM software, adopting non-singular elements and Newmark integral method, through least square fitting. The method could be used widely for general purposes, it was beneficial and necessary for using linear elastic fracture dynamics to solve practical engineering problems.
