<p>Hello Peter,<br>As per your suggestions, I applied the loadsteps with time integration turned off for first step. <br>After running the simulation, following are the results,<br>Total deformation-<\/p><p><\/a><\/p><p>The disc appears to be expanding for total deformation and joint probe (relative rotation).<\/p><p>Equivalent stress as shown below-<\/p><p><\/a><\/p><p>Joint probe as shown below-<\/p><p><\/a><\/p><p>This result is obtained for modified density after multiplying by a factor of 1000.<\/p><p>I’ve also tried a coupled field transient for this disc brake.
