| Abstract: | The boundary integral equations are presented and the corresponding supple-mental integral equations are also decived for thermal-plastoelastic problems in plane defor-mation, which can be regarded as a special kind of plane problems. The computation modelspresented can transform the three-dimensional problems into the two-dimensional ones,which will lay a foundation for the application of boundary element methods to solve theproblems of welding residual stresses in thick plates. |
