초록

소성스핀을 취급하기 위한 이론을 살펴보면 개념적으로 현저히 다른 세가지로 압축된다. 또한 재료직조 현상이 소성스핀의 근원이라고 알려져 있지만, 그 지배인자와 발생근원에 대하여 아직 충분히 연구되어 있지 않다. 따라서 앞으로의 연구에 올바른 방향을 제시하기 위하여 소성스핀의 기본적인 거동에 대한 연구가 요구된다. 본 연구에서는 체심입방격자 다결정의 소성스핀 시뮬레이션을 통하여, 소성스핀의 거동을 조사하였는데, 재료직조, 변형경화, 변형속도, 하중역전 등의 영향을 검토하였다. 소성발생원인으로 재료직조현상이 강조되었고, 이에 관련한 주요지배인자를 제시하였다. 무차원 소성스핀은 변형속도, 재료경화에 영향을 받으나 재료직조와 관련한 인자와 비교하여 그 영향이 작게 나타났다.
