THE sraxss distribution in a plate into which a crack is generated has been studied by many investigators. The most earlier contri&tuions are due to Inglis[ll, who studied the stresses around an elliptic hole in an iu8nite plate and to Westergaard [2], who treated the crack problem by the complex. v
