To obtain the original sheet and the amount of ductile components Pressing dimensional finite element method and reverse

The purpose of this document delivery method to obtain the optimal initial sheet is Pressing parts. In this point of view how the pieces of ductile rupture and shrinkage is predictable using this method in the design stage is very convenient format. In other words, having the dimensional pieces, profile sheets and the mechanical process of hysical conditions can achieve all these goals. In this way the overall deformation theory Khmyrsany (plasticity) is used. According to the basic sheet on page Qrardashtn horizon, the elevation change at any point is unclear and the issue of two-dimensional case is reduced to three dimensions in the reduced volume of calculations is highly effective. In order to access the most appropriate initial guess in solving systems of equations, a special method Tsvyrkrdn elements in the piece on page three dimensions on the horizon is used. In addition to solving the equations system card optimal initial Krnshhay the main component is determined. The results of this technique for several industrial piece with experimental results and also compare the available commercial software is located.
