| 内容記述 | The aged piping of a nuclear power plant has possibility to have some defects such as SCC cracks and local thinning. In order to evaluate tolerance limit of the degraded piping, a series of large scale four-point bending, low cycle fatigue tests for the degraded pipes were carried out as a part of the "Aged Piping Committee" project sponsored by National Research Institute for Earth Science and Disaster Prevention. The purpose of the study in this paper is to estalish 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 or ovaling/buckling behaviors observed in the experiment can be simulated well through the finite element analysis. | |||||||||||||||||||||||||
