Energy transformation at the friction interface of a brake has been studied in
a system where resin bonded composite friction material is applied to a metal
mating body. A time-step simulation of braking friction was developed using
finite element techniques, based upon the PAFEC 75 program, combining
calculations of interface contact, pressure and friction force distributions
with transient temperature analysis. Only compressive normal forces and
tangential friction forces are transmitted across the interface, and these were
assumed to be related by Amontons' Laws; the coefficient of friction so
defined being considered constant for the purposes of the analyses presented. [Continues.]
