Simulation of Sheet Metal Forming – Necessary Developments in the Future
1 Keynote Paper NUMISHEET 2008; Interlaken, 1.-5. September 2008 Abstract: The industrial forming simulation used today is the result of a development process during the last two decades. A main focus of this process was the continuous optimization to characterize the material properties. The presentation will give an overview of the simulation technology challenges arising from the need to imp...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
متن کاملExpert System Applications in Sheet Metal Forming
Expert system can be defined as an intelligent computer program, a repository of knowledge, a set of rules, like a human consultant, all aiming at delivering accurate solutions/suggestions to a problem at any level, say during plan, design, manufacture, and quality control. Some of the important definitions are quoted here. “An expert system is a computer system used to distribute the expertise...
متن کاملTolerance transfer in sheet metal forming
A literature review of sheet metal forming errors as well as geometrical dimensions and tolerances (GD&T) shows that the theoretical means for the allocation of process tolerances with respect to GD&T are insufficient. In order to judge the influence of geometrical process errors (e.g., angular errors of bends), two typical sheet metal designs with parallelism and a position tolerance are studi...
