A Study on Plastic Behaviour of Cruciform Welding Joint with Variation of Contour

십자형(十字形) 필렛 용접(熔接) 이음의 형상변화(形狀變化)에 따른 소성적(塑性的) 거동(擧動)에 대한 연구(硏究)

In this paper, plastic behavior and plastic strength of cruciform fillet welded joint under tension is investigated by finite element method. Attension is focussed, in particular, on the effect of geometry of fillet weld including its contour, size and penetration. And the approximate analysis of welded joint have been carried out from a simple model constructed by three zone, ie, base metal, heat affected zone, and weld metal.
