초록
본 연구에서는 편면도금 강판과 복합조직 고장력 강판간의 이종 용접재의 피로거동을 연구하고져 한다. 즉 유한요소법으로 응력분포를 조사하고 그 결과와 피로균열발생 위치를 비교 검토해 보고자 한다.
The influence of monogalvanized layer to fatigue strength of two different mating metal specimens (HS*GA, HS*GAB) of high strength steels(HS) and of monogalvanized steel sheets(GA, GAB) were investigated under tensile-shear repeated load, and hardness test. Some of the results are; (1) The main cause of crack initiation and growth at high load range is plastic bending hinge. (2) In low load range, the cracks initiated near the nugget front where the hardness variation is steep.
