The Development of Static-explicit Rigid-plastic Finite Element Method and Application to 2-dimension Sectional Analysis

2차원 단면해석을 위한 정적-외연적 강소성 유한요소법의 개발 및 적용

In rigid-plastic finite element method, there is a heavy computation time and convergence problem. In this study, revised rigid-plastic finite element method Will be introduced. This method is the way that restrict the convergence interval. In result, convergence problem and computation time due to large non-linearity in the existing numerical analysis method were no longer a critical problem. It is expected that various results from the numerical analysis will give very useful information for the design of tools in sheet metal forming process.
