Abstract
In order to predict the elastic-plastic fracture toughness for metallic materials, Finite Element Method(FEM) was used for analysis of compact tension specimen. ASTM E399 test procedure was adopted for simulation of FEM. The Load-Crack Mouth Opening Displacement curve obtained from this analysis was used to detect the crack initiation point and determine the elastic-plastic fracture toughness
금속재료의 탄소성파괴인성치 측정을 위해서 ASTM E399 시험법에 따라 단순 인장 시험편을 사용하여 유한요소해석을 하였으며 여기에서 얻어진 하중-균열개구변위 곡선을 이용하여 균열개시점을 찾고 이 점에서의 파괴인성치
