The benchmarks focus on three different theoretical fields. The theoretical prediction of forming limit curves, the modeling of spring back under the influence of stretching forces generated by the complex deformation state induced by draw beads and on the press hardening process which recently was introduced for crash resistant body components.

BM 1 - Virtual Forming Limit Curves
 |
This benchmark is provided by the BMW Group. It
analyzes the theoretical and numerical prediction of beginning material
instability by local necking during forming of ductile sheets with
various thicknesses. The objective of this benchmark is to verify the
applicability of existing or new failure criteria for this prediction.

BM 2 - Virtual Drawbead Models ("S-Rail-08")
 |
This benchmark is provided by Daimler AG. The objective of this benchmark is
to evaluate the capability of the simulation to model different drawbead
scenarios with respect to the prediction of drawing and springback. For this
benchmark, the well known S-Rail was chosen. Subscription and download (zip, 15 MB, updated 29/02/2008) (requires login) |
BM 3 - Continuous Press Hardening
 |
This benchmark is provided by Audi. The aim is the exact virtual modelling of the
continuous press hardening process of a B-Pillar with the prediction of failure
by cracks and the local degree of hardness. Subscription and download (zip, 12 MB, updated 21/08/2007) (requires login) |
The material for all three benchmarks is provided by Novelis and ThyssenKrupp Steel.
