In the paper the modelling of thermo-mechanical effects in the process of friction welding of corundum ceramics and aluminium is
presented. The modelling is performed by means of finite element method. The corundum ceramics contains 97% of
Al2O3. The mechanical and temperature fields are considered as coupled fields. Simulation of loading of the elements bonded with the heat flux from friction heat on
the contact surface is also shown. The heat flux was modified in the consecutive time increments of numerical solutions by changeable pressure
on contact surface. Time depending temperature distribution in the bonded elements is also determined. The temperature distribution on the
periphery of the cylindrical surfaces of the ceramics and Al was compared to the temperature measurements done with a thermovision camera.
The results of the simulation were compared to those obtained from the tests performed by means of a friction welding
machine |
