Band brakes operated by pressing a thin layer of brake pads against a rotating drum. This results in generating a frictional force that results in deacceleration of drum. The frictional force generate heat that adversely effect the performance of the braking pads which results in wearing of the pads. Thus fatigue performance of braking pads is effect by combined response of temperature and mechanical pressing. Hyperplastic material model based on reduced polynomial is used to model the braking pads. While the results from Abaqus is exported to Fe-safe and worst life cycle is approximated using Rainflow cycle counting algorithm. Results shows that with a by applying extreme mechanical displacement force that worst cycle is 578 hours and for normal pressing its as high as 2e11 hours.
