This multiphysics model examines temperature and heat induced stresses
for one braking cycle in a brake disc assembly, and involves coupling
of the stress-strain and heat transfer physics modes. The braking
process consists of applying a brake pad to the front part of the disc
which induces heat through friction, and results in build up of
stresses and strains in the brake disc. Both rotational and axial
symmetry is used to reduce the computational cost. Simulations have
been performed with the geometry and material parameters given in the
reference  resulting in the final temperature and stress
fields shown in the following figures.
The resulting temperature and stress curves on the disk surface at
various times agree well with the results computed with the Nastran
FEA software .
The video below shows how the stresses at various points increase as
the temperature builds up due to friction.
