Analysis of time varying temperature dependent phenomena is a tedious task. In the present work finite element analysis (FEA) of locomotive wheel and brake block interface has been made to study efficiently the processes such as temperature responsible for initiation of wheel wear and roughness. The main consideration in the study is the thermo-mechanical interaction between brake block and wheel rim during braking. Coupled transient thermal and quasi-static mechanical FEA with thermo-mechanical simulation capability based on load vector coupling have been conducted to study the process. For validation of simulation results obtained using FEA, it has been compared with the experimental results available in literature. A maximum error of 12.5% was observed in the simulated result which might have been introduced due to assumed heat partitioning factor or roughness of the surface.
