Distribution of Stress Across the Thickness Near a Crack Tip in a Plate Subjected to Approximate Cylindrical Bending

摘要

The inplane stress distribution across the thickness is determined by two different methods for a plate loaded in bending. It was found from experimental work that the use of a nonlinear function for the inplane stress distribution across the plate thickness does not result in any significant improvement in the accuracy of the theory for the geometry of through cracks in thin and moderately thick plates. The maximum actual transverse normal stress was approximately one-half the plane strain value.
