“…It was observed that before the pin is worn, the pin bends due to the action of friction. 29 Therefore, the contact stress of the pin in the initial time frame is highly concentrated at one side than the other. As the time duration of the analysis increases, the concentration of contact stress is observed to decrease until an equilibrium value is obtained, where the contact pressure contour is relatively uniform.…”

“…The contact area increases, and the contact pressure profiles become more uniform as wear progresses, with a progressive decrement of the maximum contact pressure value. He et al 29 proposed a spur gear dynamic model that includes the mesh stiffness of the worn tooth profile. Based on the Archard wear model, a method for calculating tooth wear depth that takes into account the worn tooth profile and dynamic mesh force is also proposed.…”

Performance of dental materials is influenced by the abrasion and wear qualities of the materials in contact. Despite major advancements in dental materials over the previous few decades, restorative materials, particularly composite resins, continue to wear out. Wear resistance is directly influenced by several composite resin composition and structure characteristics. The focus of this research is to explore the tribological properties of two commercially available dental composite materials using ANSYS software (Tetric N-Ceram and Z350 Dentin Shade). In the experiment, a simple tribo-system that complies with American Society for Testing and Materials (ASTM) G99 is utilised, consisting of a cylinder-shaped pin that can be deformed, rotating around a disc under wet conditions. A comparison of Z350 dentin shade and Tetric n Ceram simulations for the same load and simulation time revealed that the former material had greater wear resistance. Simulation results showed that as the stress on the pin increases, wear for both materials increases, which is supported by experiment data from the pin-on-disc tribometer setup.

“…Employing the finite element method opens more possibilities to improve accuracy, which is why Bajpai et al [ 26 ] combined the finite element method and the Archard model, using the iterative method to consider contact changes due to wear. Because mechanical elements like gears, bearings, etc., are dynamically loaded components, it is also useful to consider time-varying sliding distance and time-varying contact load in the wear analysis to make results more accurate [ 27 , 28 , 29 , 30 , 31 , 32 ].…”

This study presents a computational model to determine the wear behaviour of polymer gears. Using PrePoMax finite element numerical calculation software, a proposed computational model was built to predict dry rolling/sliding wear behaviour based on Archard’s wear model. This allows the calculation of the wear depth in each loading cycle with constant mesh updating using the finite element method. The developed computational model has been evaluated on a spur gear pair, where the pinion made of POM was meshed with a support gear made of steel. The computational results obtained were compared with the analytical results according to the VDI 2736 guidelines. Based on this comparison, it was concluded that the proposed computational model could be used to simulate the wear behaviour of contacting mechanical elements like gears, bearings, etc. The main advantage of the model, if compared to the standardised procedure according to the VDI 2736 guidelines, is the geometry updating after a chosen number of loading cycles, which enables a more accurate prediction of wear behaviour under rolling/sliding loading conditions.

“…Although models have their own limitations, one of their advantages is not to have unknown physical factors affecting the results, since the equations representing the model are set by the programmer or user. Computational methods and models such as the FEM and Archard's wear model (or a modified version) have been broadly investigated in the literature [18][19][20][21][22][23], including for specific applications (e.g., gears [24]). Recently, Mukras [25] presented a thorough review of the literature on simulation and prediction of wear.…”

A Closer Look at the Contact Conditions of a Block-on-Flat Wear Experiment

Specific wear rates of tribosystems always rely on the data obtained from wear experiments. Nonetheless, the events taking place during an experiment may often lead to wide variations and low repeatability of the results. In this work, the authors attempt to take a closer look into the dynamic contact conditions of a dry linearly reciprocating block-on-flat wear experiment. The finite element method and Archard’s wear model are used through COMSOL Multiphysics® 5.2a and LiveLink™ for MATLAB® software to model the wear and study the influence of different conditions of the block surface and alignment of the sample. Changes of the geometry of the block and the contact pressure are quantified for several back and forth motions, using an extrapolation scheme in the wear modelling methodology. The tracking of such changes allow a dynamic overview of how the block contact area and the contact pressure distribution change throughout time. The results show how the assumption of a constant contact area and use of a nominal contact pressure in calculating the wear rate in such experiments can be inappropriate, especially in the presence of roughness and misalignments of the block.
