A General Tool Surface Contact Search and its Application to 3-D Sheet Forming
일반적인 금형면에서의 접촉탐색과 3차원 박판성형에의 응용
Abstract
In the present study, a general tool surface contac search ad check algorithm is proposed. A general tool surface is described by triangular FE mesh. To check a proposed algorithm, clover cup and L-shape cup deep drawing processes are calculated. The elastic-plastic FEM using SEAM (Shear Energy Augmented Membrane) element is adapted for numerical stability.
