    <description descriptionType="Abstract">&lt;p&gt;The modeling of thermal and mechanical effects during braking has become increasingly&lt;br&gt;
important in product design in different transport means, road vehicles, airplanes, railway&lt;br&gt;
vehicles, and so forth. The thermal and mechanical analysis is a very important stage in the&lt;br&gt;
study of braking systems, especially of railway vehicles where it is necessary to brake huge&lt;br&gt;
masses because the thermal load of a braked railway disc prevails compared to other types of&lt;br&gt;
loads. In the braking phase, kinetic energy transforms into thermal energy resulting in intense&lt;br&gt;
heating and high temperature states of railway discs. Thus induced thermal loads determine&lt;br&gt;
thermo-mechanical behavior of the structure of railway discs. In cases of thermal overloads,&lt;br&gt;
which mainly occur as a result of long term braking on down grade railroads and braking to&lt;br&gt;
standstill on a flat railroad, the generation of stresses and deformations occurs whose&lt;br&gt;
consequences are the appearance of cracks on the discs, brake judder, thermo-elastic&lt;br&gt;
instability and finally brake disc failure. The importance to precisely determine the&lt;br&gt;
temperature distribution caused by the transfer process of the heat generated during braking&lt;br&gt;
due to the friction on contact surfaces of the braking system makes it a challenging research&lt;br&gt;
task.&lt;/p&gt;</description>
