Disc Brake is an essential Component of
automotive braking system. Its generally subjected to
high amount of temperature and pressure for
continuous stopping of vehicles. The literature shows
most of work is done on the structural strength and
transient temperature impact on disc brake. No work is
executed on crack development at high stress intensity
point on the disc brake surface.
150cc Pulsar two-wheeler is considered for
designing and analysis of the disc. 3D Modelling of the
disc brake is done by 3D Modelling software Solidworks
and All the design parameters are taken from the
literature papers. Finite Element analysis software
ANSYS workbench 15.0 is used for Structural, Thermal
and Crack development analysis at actual working
condition of the disc brake.
Finite element analysis on the disc brake shows
that, Crack initiation taken place at High intensity point
on the crack surface and Crack Development will
happen when J Integral value of the Simulation crosses
the SIF of the Material. FEA simulation also show the
rate at which crack develops and direction of crack
