And then, substituting stress and displacement into basic formula of strain energy release rate, computing formula for strain energy release rate of mode III, mixedmodecrack tips are direved.
In this paper, fracture mechanism, position and direction of crack initiation of mixedmode fracture in several ductile materials are tested, and stress distributions of which are analyzed.
An expression of energy difference rate in a plate of non-uniform thickness with a crack of mixedmode under both body force and surface tractions in a non-uniform temperature field is derived.
