LOW CYCLE FATIGUE ANALYSIS OF LOCALLY THINNED PIPING

Abstract

The purpose of the study in this paper is to establish analytical approaches by which the failure behaviors of the locally thin-walled piping can be simulated well against seismic loading. The summary of results obtained through the present study is as follows. Fully three dimensional elasto-plastic analyses have been carried out for the locally thin-walled piping by using ABAQUS. It has been found that the ratcheting behavior observed in the experiment can be simulated well through the finite element analysis.
