✦ Synopsis

An explicit expression of the amount of elastic energy release for crack extension under general two dimensional loading is presented through linear elasticity theory. It is shown that the direction of crack extension under general plane loading can be obtained directly by the minimization of the potential energy with respect to the crack direction. The minimization process indicates that the crack extension direction provided by maximum stress criterion is the same as that derived from minimum potential energy,

## A B S T R A C T The "energy density theory" of G. Sih is extended to investigate the direction of initial crack extension at the tip of blunt cracks (notches) in combined Mode 1-Mode 2 loading. Three different governing strain energy density functions are postulated for comparison, and each is
