Abstract

본 논문에서는 균열이 존재하는 구조부재에 충격이나 폭발하중이 가해진 경우 동적응력확대계수를 구하는 방법들은 논의하고 특히 코오스틱 실험법 및 수치적으로 코오스틱 곡선을 구하여 동적응력확대계수를 구하는 과정을 자세히 설명하였다. 폭발 및 충격에 의한 구조물의 파괴해석은 이와 같은 하중을 받는 압력용기, 빌딩, 초고속선, 해군 함정 등의 파괴강도설계 및 안전성 평가에 핵심기술로 대두되고 있으며 또한 우주항공산업, 고속전철, 암반역학 등의 여러 분야에서 중요한 의미를 갖는다. 따라서 앞으로도 균열진전 및 정지조건, 탄소성 동적파괴해석 및 재료의 충격거동 등에 대한 연구들이 계속되어져야 할 것으로 사료된다.
