While such investigations yield differing effects dependent on the situation, the common observation of a temperature change has been associated with the presence of mechanical energy, which is required to overcome frictional resistance as sliding at the contact interface occurs. The energy, dissipated through conversion into thermal energy, is manifested as a temperature rise. At the microlevel, this increase can be substantial. A localized change in material properties, an enhancement in chemical reactivity, and ultimately, failure of the mechanical system can result. Attempts to quantify temperature changes have led to the development of straightforward equations associated with the type of...
