Prediction of Welding Deformation of Underframe 总被引:1,自引:0,他引:1
IntroductionWelding deformation is a common and impor-tant problem in industry.In the last decades re-searchers have made efforts to predict and controlwelding deformation.There are usually three waysto determine the welding deformation:1 experi-ential formulas.2 Thermal elastic- plastic FEMmethod.3 Inherent strain method based onFEM[1~ 3 ] .Experiential formulas are only fit for simpleshape structures.Current thermal elastic- plasticmethod usually simulated either small or simplestructur… 相似文献
