Study of High Speed Blanking Process with the C-NEM
Résumé
The C-NEM is a new approach that we apply to solve mechanical problem in the context of finite transformations as encountered in forming process simulation. The C-NEM (Constrained Natural Element Method) is based on the Voronoi diagram associated to the nodes spread on the studied domain. The Voronoi diagram is constrain to respect the geometry of the domain boundaries. Its ability for constructing the interpolation when the domain becomes highly distorted makes of that approach an appealing choice for simulation forming processes as for example 3D cutting and blanking. In this communication we present some aspects related to the C-NEM approach and we show its ability to simulate kinematics encountered in high velocity blanking process.
