Development of 3D Sheet Metal Forming Analysis Program by explicit finite element method

외연적 탄소성 유한요소법에 의한 3차원 박판금속 성형해석 프로그램 개발

In this study, 3D sheet metal forming analysis program is developed by explicit finite element method. In this program, analysis flow just follows the real engineering process to provide the user intuitive understanding and smooth contact alorithm improves the accuracy of stress prediction. The capability of this program are demonstrated by various examples.
