A Study of Forming Analysis by using Dynamic-explicit Finite Element Method in Can-container Production Process of Multi-Stage Assembly

Multi-Stage 조립품인 캔-용기 생산 공정에서 동적-외연적 유한요소법을 이용한 성형해석에 관한 연구

In the present work a finite element formulation using dynamic-explicit time integration scheme is used for numerical analysis of multi-stage stamping processes. The lumping scheme is employed for the diagonal mass matrix and dynamic explicit formulation Multi-Stage stamping is analyzed by using dynamic-explicit finite element method. Further, the simulated results for the panel stamping processes are shown and discussed. Its application is being increased especially in the stamping industrial area for the cost reduction, weight saving, and improvement of strength.
