✦ Synopsis

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 before onset of fracture, represented through the stress intensity factors (SIF's) K,(i= I, II), but also on the angle 00 under which the branch crack propagates.

Using the maximum energy release rate criterion as the fracture criterion, Shen and Lee [2] extended Nuismer's work and developed expressions for the angle 0 of initial crack extensien under which G reaches its maximum G,~.
