| Abstract: | In this paper, a new analytical-engineering method of closed form solution for stress intensity factors of shear modes for 3-D finite bodies with cracks is derived by the time saving energy release rate method. Hence a complete series of useful results of stress intensity factorsK II andK III can be obtained. And the results provided by this method are in good agreement with some obtained by other methods. |
