Advanced press shop support
Corus offers on-site press shop support using state-of-the-art PHAST™ strain measurements and extensive practical experience. Corus uses this system to measure forming strains and visualise material flow in panels. The results are used by Corus forming experts to advise customers in achieving a stable production process.

Getting parts right first-time
Corus has developed In-Form™, a highly innovative method allowing portable, quick and accurate measurement of 3D geometries. The combination of this technology and our extensive experience in FE modelling enables Corus to provide state-of-the-art support in different stages of sheet metal processing. In-Form™ can be used to support and reduce the time of tool tryouts and also improve the forming reliability for critically stamped parts.

Corus-Vegter material model
Increased accuracy in PAM-STAMP™ 2G forming simulations The automotive indystry uses PAM-STAMP™ for formability analysis to reduce the cost and lead time of new vehicle programmes. To assure that accurate analysis of the feasibility and processing of an automotive part can be made, Corus developed the Vegter model which has been implemented in PAM-STAMP™.

Friction in sheet metal forming
Friction is of importance in sheet metal forming processes due to the relative motion of surface contacts during material deformation. Besides mechanical properties of the sheet, friction has the largest influence on the development of stress and strain across a formed part. Therefore controlled friction can be the determining factor to guarantee a stable process with a minimal amount of defects.

Analysing roll forming
Longitudinal strain calculations with COPRA® software When considering the forming of newly designed profiles on existing production lines the number of roll forming passes must be sufficient to produce acceptable products. COPRA®, a programme of Data M, can calculate the longitudinal strain level between the passes, which is one of the most significant parameters in roll forming technology. By doing so, COPRA® offers the possibility to analyse and optimise newly designed roll forming processes before making new forming rolls.

Simulating roll forming
Analysis and prediction of roll forming processes Using simulation techniques the behaviour of metal sheet during roll forming and profiling can be analysed. To this end different methods are used: a simple analytical method that is fast but not too accurate, and the more accurate but slower and more complex Finite Element method.

Defects in roll forming products
3D finite element analysis with COPRA® FEA RF software Sometimes roll formed products suffer from defects caused by distortion of the profiles’ edges or webs. Some of these defects can be attributed to the set-up of the roll forming passes. One of them is the occurrence of ‘wavy edges’ in light gauge profiles. A 3D finite element analysis offers the possibility to visualise these defects and show the effects of countermeasures against the defect concerned.
