Structural analysis of tube deformation in a roller pump
Geometry of pump roller and medical tube
In many fields of biomedical technology, e.g. roller pumps, it is very important to investigate both the medium flow and the mechanical stresses and strains on the surrounding structure.

The present example shows a structural analysis of the deformation in a pump tube with account taken of the friction between tube and pump bed, tube and roller and within the tube itself.

The highly non-linear behaviour of the elastomer tube material is taken into consideration.
