RECTANGULAR TENSILE SHEET WITH EDGE CRACKS,
ARMY MATERIALS RESEARCH AGENCY WATERTOWN MASS
Complex variable methods are applied to the plane elastic problem of a rectangular tensile sheet with edge cracks. A mapping function is used which is sufficiently flexible to account for both variations of crack length and lengthwidth ratios of the sheet on the stresses local to the crack tips. Numerical results are carried out and compared with the approximation derived from Westergaards solution. Author
