Tribology of Elastomers

Description

This book highlights the tribological behavior of elastomers by investigating the effect of operating variables such as, the applied load and the abrasive particle size, and the materials’ mechanical properties such as, tensile strength, elongation at break, hardness, and tear strength by the experimental, statistical and analytical methods. It is found that the wear mechanism is mostly friction wear, which is mixed with fatigue wear and abrading under higher applied loads or larger abrasives. The statistical method shows that the abrasive particle size has the highest contribution followed by the applied load on the wear process. Wear equation is developed to predict the wear rate considering the trends of the input variables.
