H型钢焊接残余应力的三维有限元分析

Three-dimensional finite element analysis of welding residual stress in H-beams

采用通用有限元软件ABAQUS对普通H型钢的焊接残余应力场、变形场进行了数值模拟,并和现有公认结果进行了对比。结果表明,数值模拟方法真实可靠,纵向残余应力影响较大,应引起足够的重视。

Abstract： The paper simulates the field of welding tress and deformation of normal H-beams using general finite element software ABAQUS. And compare the results with the existing recognized results. As a result, the numerical simulation method is reliable, the longitudinal residual stress has a greater impact, which should receive enough attention.
