  "abstract": "<p>The modeling of thermal and mechanical effects during braking has become increasingly<br>\nimportant in product design in different transport means, road vehicles, airplanes, railway<br>\nvehicles, and so forth. The thermal and mechanical analysis is a very important stage in the<br>\nstudy of braking systems, especially of railway vehicles where it is necessary to brake huge<br>\nmasses because the thermal load of a braked railway disc prevails compared to other types of<br>\nloads. In the braking phase, kinetic energy transforms into thermal energy resulting in intense<br>\nheating and high temperature states of railway discs. Thus induced thermal loads determine<br>\nthermo-mechanical behavior of the structure of railway discs. In cases of thermal overloads,<br>\nwhich mainly occur as a result of long term braking on down grade railroads and braking to<br>\nstandstill on a flat railroad, the generation of stresses and deformations occurs whose<br>\nconsequences are the appearance of cracks on the discs, brake judder, thermo-elastic<br>\ninstability and finally brake disc failure. The importance to precisely determine the<br>\ntemperature distribution caused by the transfer process of the heat generated during braking<br>\ndue to the friction on contact surfaces of the braking system makes it a challenging research<br>\ntask.</p>",
