Simplified Modeling for Analyzing 3-D Deformations of Spot-welded Structures

저항 점용접의 3차원 변형 예측에 대한 간이 모델링 기법

A simplified analysis method is proposed in this paper, through which the deformation due to spot welding is obtained. In order to analyze the spot welding process, the finite elements are axisymmetrically modeled, and the results from them are used for analyzing the deformation of spot welded structure. It takes more little time in this simplified analysis than the analysis by 3-D continuum elements, and this analysis produces the results that nearly agree with the measured data.
