“…Indentation experiments using varied metallic materials can be easily found [23][24][25], but soft and sharp non-metallic indenters are much rarer in the literature. In this fashion, the experiments conducted by Engelder and Scholz [26] and their results deserve special attention.…”

Abrasive wear is highly dependent on the characteristics and properties of abrasive particles. Their hardness and size can define the severity of abrasion in terms of wear rates. Typically, critical values have been empirically determined to define the transition between mild and severe wear. This review aims to update some of the issues related to these critical values and their relations to abrasive wear. After presenting the current state-of-art, the following items are discussed: a) the scratchability of materials; b) the particle fragmentation associated with size effects; and c) description of abrasion severity.

Understanding the contact characteristics of rough surfaces is essential to explain engineering phenomenon in interface. In order to improve accuracy of contact model, a novel simplified fully plastic contact model of sphere asperity was proposed considering material properties based on fractal theory. Firstly based on Von Mises yield criteria maximum contact pressure factor was derived. Secondly relationships taking into consideration strain hardening were proposed to describe contact area based on definition of the fully plastic contact area index and contact pressure. Then the critical interference at inception of fully plastic deformation was derived. Lastly validations were conducted for different materials. The results show that present work is remarkably consistent with experiment results and has higher accuracy than other models.
