摘要
用在裂纹动态奇异解析解上叠加动态有限元法,来计算动态应力强度因子。它推广了钱伟长等人的工作,所得结果可用于Ⅰ,Ⅱ型及Ⅰ,Ⅱ混合型裂纹体的动态应力强度因子的计算。
Is presented an approach based on the superposition of normal finite element method on dynamic singular terms , in the whole field of the crack to calculate the dynamic stress intensity factors . This approach endeavors at an extension to work by Prof .Chien Weichang & others and can be used to calculate the dynamic & static stress intensity factors for mode 1 and mode 2, as well as for the mixed mode .
