Fem Modeling of Thermo-mechanical Interaction in Pre-pressed Rubber Block

The FEMLAB code based on weak formulation of PDE’s problem was used at a solution of feedback thermo-mechanical interaction in pre-pressed rubber block used for resilient elements of the composed tram wheels. The structural motion and heat conduction equations are solved interactively as time dependent problems. The equality of heat energy density and dissipation energy density realizes the coupling between the equations. The dissipation energy density is computed according to the assumed proportional damping model. In the paper the results of thermo-mechanical processes in case of a plane strain deformation under static pre-pressed and cyclic dynamic loading are presented and analyzed.
