Nuismer [1] derived an expression for the energy release rate G for mixed mode fracture in which case the initial angle of crack extension is not equal to zero, i.e. the crack extends in a non-self-similar manner. He developed a generalized relation in which G depends not only on the stress state be
## A B S T R A C T A critical analysis was made on the relationship between the energy release rate G and the stress intensity factors for non-coplaner crack extension under combined Mode I, II and III loading. Developing a method different from the application of Bueckner's equation, the equation
In this paper\ a new analytical!engineering method of closed form solution about stress intensity factors of shear modes for 2!D \_nite bodies with eccentric cracks is derived by means of the energy release rate method and relevant given 1!D stress intensity factors[ This method is both accurate and
