[구조강도부문] 점용접 T-형 결합부재의 응력해석과 피로설계에 관한 연구
2001
As a fundamental investigation for developing an actual body design method applying the fatigue data of single spot welded lap joints accumulated by many researchers so far, analyzed the stress distribution and evaluated fatigue strength on tile spot welded t-type member. And, possibility of fatigue design for spot welded t-type member and bus window pillar member using the fatigue data of single spot welded lap joints was investigated. From the results, it was found that even though there are some difference in fatigue strength between single spot welded lap joint and the actual members under the same fatigue life, the fatigue design criterion which is equivalent to design life can be predicted by correction between them.
