A direct method based on the boundary element equation approach was proposed in a previous paper (Li and Keer, 1992, Int. J. Solids Structures 29, 2735-2747) to solve tensile crack growth problems for arbitrarily distributed loads. This method is extended to solve crack growth problems under an arbitrary shear loading. An equation is derived which gives an explicit relation between the crack front variation and the resulting changes in the energy release rate. This method is then applied to determine the yield zone of cracks having an assumed shear resistance of the Dugdale type. Numerical results show a significant Poisson's ratio effect of the material on the shape of the yield zone. Averaged quantities appear quantitatively similar to results from simpler approximations.
