边界元辅助二维焊接残余应力求解的探讨

Investigation on the solution of BEM aided twodimensional welding residual stresses

提出了边界元辅助二维焊接残余应力求解的方法，该方法用构件的边界位移量──焊接变形来求解焊接残余应力．编制了相应的计算程序，通过两个算例，验证了此方法的可行性．

A method is proposed for the solution of two-dimensinal welding residual stresses by means of boundary element method, which is a procedure for solving the problem of welding residual stresses with the help of boundary displacements of the structures of the welding deformations.The computor programme is coded for the solution and the feasibility of the procedure is verified through two examples performed.
