열탄소성 해석에 의한 원주용접 열변형에 대한 연구

(A Study on the Thermal Deformation of Circumferential Welding by Thermal Elasto-Plastic Analysis.)

Residual stresses and thermal deformation of a structure due to welding are very imfortant factors for a weld design. It has been carried therretical analysis to invesitigate influence of heat flux to residual stresses and thermal deformation producted by curcumferential welding. Temperature,stresses and deformationn are obtain as a function of circumferentisl drgree and distance from welding center line. These result can applicate to predict and remove the deformation or residual stresses built up by welding.
