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.
