Thermomechanical Cracking Due to Moving Friction Loads.

Abstract

The investigation uses several mathematical models to study the possibility of fracture initiation by dry friction and the configuration of fracture. The general study of friction cracking has a special application in marine seals. The purpose of this study is to extend our understanding of the problem by looking into the thermomechanical state of stress in a mechanical part resulting from the traversing of a single asperity or periodic asperities over its surface. The understanding of such a failure process could be used to improve the design of devices such as marine seals by alleviating the problem of friction cracking.
