Power transmission plays an important role in automobiles. Since the concern regarding safety in automobiles has been considered as a top priority, it is very much important to have a complete control over vehicle to make it stop. Brakes are the power interruption devices which absorb the kinetic energy of vehicle and bring it to the rest condition. Once the brakes are actuated, heat is generated due to the friction between pads and rotating disc. This heat generated is responsible for high temperature of the disc. As brakes convert friction hito heat, it must be dissipated through it in order to have limited temperature range of the entire system. Under this consideration drums brakes have been replaced by disc brakes as they are more efficient under steady and instantaneous braking conditions. In this paper, models were designed by using CATIA-V5 and then imported to ANSYS 16.2 for static structural and thermal analysis. The designing of discs was carried out considering its application for a two wheeler of 200-250 ce engine capacity. The aim of this paper is to study the heat distribution and the overall deformation of the discs having different cut patterns. Further an extensión to this work, an attempt has been made to investígate different aspeets like deformation and temperature distribution by varying the alloy materials for discs. This analysis has helped us a lot to understand the behavior of different materials under realistic conditions. The paper is then concluded with the best material and cut patterns in terms of strength, factor of safety and heat dissipation.
