A Study on the Fracture Resistance Curve and Effect of Side Grooves of SG365 Material
SG365강의 파괴저항곡선과 측면홈효과에 관한 연구
Abstract
SG-365 steel is an important material End used for manufacturing a pressure vessel and gas piping. In this investigation, the elastic plastic fracture toughness of this material is evaluated by the unloading compliance method according to the ASTM E8l3-97 and E1152-97 method on the smooth and side groove In specimens. The effect of smooth and side groove is studied on the elastic plastic fracture toughness. The side grooved specimen is very useful in estimation of the
