CR60강, SM58Q강과 그 용접부의 저사이클 피로특성
A Study of Low Cycle Fatigue Properties in CR60,SM50Q Steel and the Weldments
초록
Low cycle fatigue test was performed by companion specimens method to compare the properties of cyclic strain for the weldments of controlled rolling steel CR60 and welding structural steel SM58Q. And the result does not showed any difference of low cycle fatigue life between weldments. Especially, the values of coefficient of cyclic plastic strain
