A Study on the Effect of Root Gap of Double Fillet Welded Joint Considering External Forces

외력을 고려한 양면 필릿용접이음부 루트갭의 영향에 관한 연구

In this paper distribution of welding residual stress on the double fillet welded joint which exits and not exits root gap, i.e. full penetration and partial penetration is investigated by two dimensional cunduct and thermal elasto-plastic analysis. And stress distribution on notch-tip of the structure where welding residual stress regarded as initial stress and then external load is added is also investigated.
