Overview
Functionally graded materials (FGMs) have been introduced to enhance the performance of frictional systems such as brakes in the context of thermoelastic instability (TEI). Recent results are compiled to demonstrate the effects of FGM coating and nonhomogeneity on TEI.
Introduction
The concentration of frictional heating over zones smaller than the nominal frictional interface can occur during brake application or engagement of transmission clutches, leading to high localized temperatures and mechanical pressures. This feedback process, thermoelastic instability (TEI), is generally unstable [1]. The resulting high local temperatures and thermal stresses also have undesirable effects such as material transformation, thermal cracking, brake fade, and thermoelastic disk buckling. Interest in these phenomena is increasing in the automotive industry, prompted by changes in brake materials and other design improvements, in particular noise reduction and increasing comfort. A...
