라틴방격법을 이용한 고속 충격 알루미늄합금의 파괴거동에 미치는 충격자 영향 분석

다국어 초록 (Multilingual Abstract)

Structural impact problems are increasingly important for the modern defense industry, high speed transportation, and other applications due to the weight reduction with high strength. In this work, a numerical investigation on impact fracture behavior of aluminum plates with various projectile conditions such as nose shapes, velocities, incidence angles was performed. In order to reduce the iterative numerical analysis, the Latin Square Method was employed. The influence factor was then determined through the FE analysis according to the conditions. The results were evaluated by means of the statistical signification interpretation using variance assessment. It was shown that velocities among the influence factors can be the most important representing the impact absorption performance.
