Investigation of Stress, Deformation, and Cracks in the Brakes of Car Using Finite Element Method

Abstract

Twisting forces in disc brakes and friction forces between disc brakes and bearings produce heat on the disc brakes. The compression force produced by the brake piston pushes the brake pads to produce heat and deformation in the disc brakes. For the development of vehicle braking systems, wrought iron is used to make disks. However, a failure still occurs during a crack testing. The results of the analysis using the finite element method showed that the highest total deformation was 4,411 x 105 mm. The highest maximum equivalent stress (represented by the red area) is 715.48 MPa. The maximum value of SIFS (K1) around the disc brake hole is -0.9030 MPa.mm0.5, while at the edge of the disc is 5.385 MPa.mm0.5.
