Abstract
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 the derived from minimum potential energy.
