Dry Contact and Coupled Thermomechanical Analyses of Brake Disc-Pad using Finite Element Simulation

The motivation of this work is to identify the thermal effects on the structural and contact behaviour of a disc-pad assembly using a finite element approach. The first analysis is performed on the disc-pad model without the presence of thermal properties. Structural performance of the disc-pad model such as deformation and Von Mises stress is predicted. Next, thermomechanical analysis is performed on the same disc-pad model with the inclusion of convection, adiabatic and heat flux elements. The prediction results of temperature distribution, deformation, stress and contact pressure are presented. Comparison of the structural performance between the mechanical and thermomechanical is also made. Three disc-pad designs are assessed using the developed finite element model.
