Analytical model for investigation of the effect of friction power on the thermal stresses in friction elements of brakes

The influence of the change with time of friction power on thermal stresses in a friction 
element of a brake system is investigated. For this purpose, a list of ten different temporal 
profiles of specific friction power is used, which has been experimentally established for a 
single braking process. The corresponding profiles of transient temperature fields in the 
considered element are applied as input parameters to find quasi-static thermal stresses. 
Numerical analysis concerned with spatio-temporal distributions of the stresses and their 
evolutions on the heated surface is presented.
