On the assessment of variable loading in adhesive wear

An experimental procedure for assessment of adhesive wear subjected to variable loading is presented. The applicability of the Miner's rule to variable loading and an experimental methodology for determining the Miner's rule constant is described. The results of extensive pin-on-disk tests subjected to various loading scenarios reveal that the cumulative power dissipation and entropy remain relatively constant and independent of the loading sequence. These findings offer a reliable approach for estimation of wear when a component experiences variable loading.
