The solution for the crack-tip stress-intensity factors of a short crack emanating from the corner of a three-quarter plane was presented. The solution used influence functions for a dislocation lying along one of the projection lines of a three-quarter plane, together with Williams semi-infinite wedge solutions, and the result was valid for any remote loading configuration. The only requirement was that the crack was short enough to be considered to be well within the region where asymptotes governed the stress state. This general solution was applied to a specific geometry, and was compared with a calibration of the stress intensity factors for a similar geometry.
