| Abstract: |
| By using Durbin's inverse Laplace transform method, the dynamic stress intensity factor in Laplace transform domain is transformed into the result in time domain. The numerical example is given and the reasonability of the method in this paper is verified. By analyzing the calculating result, some interesting and significative conclusions are presented. |
