摘要
本文介绍了用有限元法对薄板对接焊进行热弹塑性应力分析的方法，算例说明方法的有效性以及此类焊接过程残余应力和残余变形的分布规律。
The thermoelastoplastic stress analysis of butt welded plate hy finite elementmethod is presented in this paper.The numerical example shows the effectiveness of themethod and the distributive regularity of residual stresses and residual strains in this weldingprocedure.
