A study of rolling on a cluster type mill should include analysis of the flexible rollers when the product requires high geometrical accuracy which can be affected by any deformation or deflection of the rollers.
 
The analysis of cluster type mill rolling involves multi-body contact which poses significant difficulties for many simulation codes. The ability of ADINA to solve such problems is indicative of its robust contact algorithm. The animation shows the development of plastic strain in the metal strip and the stress intensity in the rollers.
 
Note that the analysis is performed using only half the model because of symmetry. The animation shows part of the half model.
