Low Cycle Fatigue Crack Growth Analysis for the Piping with a Surface Crack(Student Poster Session)

Abstract

In this paper an analytical model, based upon the line spring model installed in ABAQUS, has been proposed in order to simulate the low cycle fatigue crack propagation. And a series of computer simulations have been carried out in order to investigate the experimental behaviors of the degraded pipes. It has been shown that the leak behavior of circumferentially cracked piping can be simulated well by the proposed method.
