THE STRESSES IN A CYLINDRICAL SHELL CONTAINING AN AXIAL CRACK,
Abstract
Using an integral formulation the coupled Marguerre equations for a cracked cylindrical shell of length 2c are solved for the in-plane and Kirchhoff bending stresses, and, among other things, it is found that the explicit nature of the stresses near the crack point depends upon the inverse half power of the non-dimensional distance from the point epsilon. The character of the combined extension-bending stress field near the crack tip is investigated in detail for the special case of an axial crack in a long closed cylindrical shell which is subjected to uniform internal pressure q sub o. Pending a complete study of the solution, approximate results for the combined surface stresses near the crack tip normal and along the line of crack prolongation are given. (Author)
