A closed form solution about stress intensity factors of shear modes for 3-D finite bodies with eccentric cracks by the energy release rate method

In this paper, a new analytical-engineering method of closed form solution about stress intensity factors of shear modes for 3-D finite bodies with eccentric cracks is derived by means of the energy release rate method and relevant given 2-D stress intensity factors. This method is both accurate and efficient. Hence a complete series about useful new results of stress factors KII and KIII can be obtained.
