Description

This study is concerned with an application of the Boundary Element Method (BEM) to 3-dimensional thermal elastic plastic analysis. A new procedure of thermal elastic plastic analysis is proposed to consider the temperature dependence of stress-strain curves and to introduce multi-linearized stress-strain curves into boundary element analysis. Some numerical techniques for BEM such as traction discontinuity treatment and tying condition were also introduced into analysis. The accuracy of 3-dimensional thermal elastic plastic analysis was confirmed by performing a thermal elastic plastic analysis of a thick-walled cylinder.
