Abstract

An analysis system for sheet metal forming(SAT_STAMP) has been developed to improve the design and tryout process by predicting the deformation behavior more precisely. This analysis system consists of forming analysis, springback analysis and post processor modules. The more accurate prediction of stress history can be achieved due to the improved contact algorithm. Continuous simulation of sequential processes can be carried out conveniently without interruption by the improved data management of the developed system. The error of data transfer between forming analysis and springback analysis is minimized using the proper shell element. Several benchmark test results and practical results are presented to show the effectiveness and reliability of this program.
