The finite element simulation is now widely used in the design of stamping tools. That is, the trial and error procedure is replaced by simulation in which defects of sheet forming processes are predicted and evaluated. The theoretical background and numerical implementation of a three dimensional f

โฆ Synopsis
A drawback of former wear simulation of deep drawing processes is that the change of wear caused by increasing the number of punch strokes was not considered. Geometry-Update-Scheme (GUS) which has been proposed at Institute of Metal Forming and Casting considers the changes of tool geometry caused by wear through interactive iterations of forming and wear simulation. The wear depth from simulation using GUS shows maximal 0.07 mm of difference from the measurement at a section of worn die-geometry. In this study, only the abrasive wear was considered.

One of the main reasons of tool failure in industrial application of metal forming technologies is wear. Typical for this kind of failure is that it affects not only the costs of the process but also the tolerances of the formed parts. The only way to control these features is to develop methods whi
## Abstract Numerical simulation of sheet metal forming process using the meshless method called reproducing kernel particle method (RKPM) is studied in this paper. Owing to limitations of meshless approximation under parametric coordinate system, a constrained reproducing kernel (RK) approximation
