Contact-Stress Analysis of Elastic-Viscoelastic Interface Conditions.

Abstract

The sliding contact (frictional) behavior of Sintered Alpha Silicon Carbide (SASC) was studied over the range of room temperature to 1100 degrees C. Both point- and line-contact configurations were evaluated under low normal forces. The results strongly indicate that a nonelastic mechanism is contributing to the contact behavior of SASC at elevated temperatures. The recovery force appears to be related to the magnitude of the nonelastic contribution. More experimental data is required to develop an analytical model to account for the nonelastic behavior at contact interfaces at elevated temperatures.
