“…Although these wear models are introduced based on conventional materials like metals, they are successfully applied and in some cases slightly modified to suit polymers and their composites [60,[216][217][218][219][220][221][222][223][224][225][226][227][228][229][230][231][232]. For example, Clark and Wong [230] extended the Bitter model for erosion of brittle materials to polymers and composites.…”

“…As compared to other more conventional reciprocating sliding tests, the specificity here is that the magnitude of the imposed relative displacement (between about 1 and 100 µm) is much smaller than the size of the contact. In other words, this means that the contact area is nearly stationary with respect to the polymer surface, which considerably simplifies the analysis of crack development as compared to large amplitude sliding tests where multiple crack interactions have to be taken into account [51,52].…”

Cracking processes in brittle amorphous polymers within sliding contacts and their relationships with bulk fracture properties are reviewed. The focus is on the use of model single asperity contacts to mimic and characterize the failure modes which can be encountered at the microasperity level during the wear of macroscopic rough contacts between polymer surfaces and rigid counterfaces. Using the resources of in situ contact visualization, crack initiation and propagation mechanisms within epoxy substrates are detailed under contact fatigue conditions. With the prospect of understanding the fundamental mechanisms involved in particles detachment from brittle polymer surfaces, it is shown how cracks locations, orientations and depths can be predicted from a knowledge of the bulk toughness and fatigue properties of the polymer by means of a fracture mechanics analysis of the contact. In the last section, the sensitivity of contact fatigue processes to molecular parameters is addressed in the case of anti-plasticized epoxy networks and random copolymers of poly(methylmethacrylate).

“…This technique enables a quantitative analysis into some special contexts of a crack-induced wear mechanism. We note that a common starting point of this technique is that some initial cracks must be placed either horizontally [5][6][7][8], vertically [9,10] or inclined [2,11,12], though real engineering components may or may not have these initial cracks. With such an assumption, the stress intensity factors were computed via linear or nonlinear FEM and the rate/direction of crack growth was subsequently determined.…”

Wear is often of definite influence in the service life of mechanical components and has been recognised as one of the major causes of failure in engineering practice. It is noted that although extensive attention has been paid to phenomenological studies like surface morphology analysis for wear assessment, the physical mechanism of wear particle formation remains unclear. This paper proposes a micro damage and fracture model to simulate the process of wear particle generation. An explicit finite element (FE) formulation is employed to capture the nonlinearities involved. Unlike existing FE analysis (FEA), any initial sub-fractures underlying the wear surface are no longer required. Crack initiation and propagation as well as the corresponding mesh updating are implemented in an automatic fashion associated with the explicit FE framework. The results presented are in good agreement with experimental observation and the reports in existing literature.
