    <subfield code="a">&lt;p&gt;A train disc brake system is used to perform three basic functions, i.e. to reduce speed of a vehicle, to&lt;br&gt;
maintain its speed when travelling downhill and to completely stop the vehicle. During these braking&lt;br&gt;
events, the disc brake may suffer of temperature, deformation and stress issues. It is quite sometimes&lt;br&gt;
that the disc brake components fail structurally and/or having severe deformation on the pad. Thus,&lt;br&gt;
this paper aims to examine stress concentration, structural deformation and contact pressure of brake&lt;br&gt;
disc and pads during braking event by employing commercial finite element software, ANSYS and&lt;br&gt;
CATIA for modeling purpose with considering the effect of unequal pressure application on the two&lt;br&gt;
opposite side of the disc which are developed due to brake line corrosion, caliper sticking, failure of&lt;br&gt;
piston seal, variation of rotor thickness and also failure of caliper bolts.&lt;/p&gt;</subfield>
