A Method of Wear Characterization Under Cut, Chip and Chunk Conditions

A new experimental method and corresponding analytical model were proposed to characterize cut, chip and chunk wear for elastomeric materials. According to the model, the wear is considered as a time-dependent nonlinear process. Experimental verification of the proposed model was conducted for four typical elastomers. It was shown that the amount of wear loss may be accurately described by the model, based on two independent material parameters. The effect of each parameter on cut, chip and chunk wear resistance was analyzed in detail. High statistical reliability was shown for the proposed material parameters and corresponding analytical predictions. The proposed method may be recommended as a robust predictor of cut, chip and chunk wear processes for rubber and, potentially, other polymer materials.
