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

Jung, Dong-Won,Lee, Seung-Hun,


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.
