内容説明
The production-costs of formed workpieces are in an increasing extent fixed through the costs for designing and manufacturing the tools. Nowadays, it is possi b 1 e to reduce these redundant tool-costs by app lyi ng modern numeri ca 1 simulation techniques such as the finite element type procedures. In thi s context, the basic ojecti ve of the workshop SUtoP (~imul ation of !:!etal F~rming ~rocesses by the Finite Element Method) was to determine and - especially - to discuss the level of finite-element-simulations of metal-forming processes with regard to technological utilization. On this purpose, eight presentations have been selected to focus the discussions onto the prime aspects such as: - technological aspects (bulk metal forming versus sheet metal forming), - constitutive laws (rigid-plastic versus elastic-plastic versus visko-pl- tic material laws), - coupled analysis (thermo-mechanical coupling), - kinematical description (Eulerian versus Lagrangian formulations, co-ro- tional formulations etc.), - numerical problems (incompressibility, integration of constitutive eq- tions, iterative and incremental schemas, etc.)
, as well as - contact problems (friction, heat-transfer, etc.). In order to promote discussions, the audience of the workshop was limited to 50 participants. Due to this fact, we had to refuse unfortunately many app 1 i cat ions. However, we hope that these proceedi ngs - whi ch also inc 1 ude the discussions in an almost complete extent - will be a compensation for those who could not attend the workshop SIMOP-I.
