Stress intensity factors in a finite length cylinder with a circumferential crack

Stress intensity factors in a cylinder with a circumferential crack are eva luated. An indirect method, the computing compliance method, is developed t o study the problem. The stress intensity factor is obtained from the displ acement response for two crack length cases, a and a + Deltaa. The finite d ifference method is used to solve the boundary value problem. Numerical exa mples are given which demonstrate the effect of cylinder length on the stre ss intensity factor. (C) 2000 Elsevier Science Ltd. All rights reserved.
