A limit load solution for a thick-walled cylinder with a fully circumferential crack under axial tension

摘要

Limit loads for a thick-walled cylinder with an internal or external fully circumferential surface crack under pure axial load are derived on the basis of the von Mises yield criterion. The solutions reproduce the existing thin-walled solution when the ratio between the cylinder wall thickness and the inside radius tends to zero. The solutions are compared with published finite element limit load results for an elastic-perfectly plastic material. The comparison shows that the theoretical solutions are conservative and very close to the finite element data.
