“…Where tan θ is the average of the individual conical roughnesses, H is the hardness of the softest surface and P is the value of the normal load applied to the abrasive particle. Equation (3) has a similar structure to Archard's equation for the calculation of abrasive wear [11].…”

The material used for 50 years in orthopedics for joint replacements is ultra-high molecular weight polyethylene (UHMWPE). Joint replacements are designed so that the metal is in surface contact with the polymeric material, and it is used in most degenerative joint disorders. A problem with joint replacements is the half-life of their UHMWPE components resulting from surface contact, leading to premature wear. This leads to the detachment of wear particles causing osteolysis. In the present investigation, a numerical simulation of the rheology of 5 µm size alumina abrasive particles applied to UHMWPE type GUR 1020 was performed by duplicating the microabrasion test. An analogy was proposed between the alumina particles observed in the scanning electron microscope (SEM) and the gravel stone obtaining a geometry similar to that of the alumina particles. A 3D scanner was used, obtaining different randomly selected gravel models. They were scanned and rendered to obtain the IGS files to be used in the finite element software. Using Archad's abrasive wear theory, the volume displaced by the abrasive particles was obtained as a function of the geometry of the abrasive grains, influenced by the entry position of one or more of the different cutting edges contained in the geometry, the hardness of the softer material, the value of the normal load and the sliding distance. Individual trace profiles were obtained by 2D profilometry and wear traces were analyzed by SEM. Explicit dynamic analysis of particle motion was used to simulate the entry, transition and displacement during the abrasive wear test caused by detached particles. The experimental results of the microabrasion test were compared with finite element analysis, demonstrating that simulation can be used as a reliable tool to obtain information about the type of wear of a material.

“…In medical applications, UHMWPE is commonly used in joint replacements due to its durability and low friction, which help to reduce wear and tear on the implant. Additionally, UHMWPE is often used in sutures for its strength and resistance to wear, ensuring that the suture remains intact throughout the healing process [1,[4][5][6]. Furthermore, UHMWPE is a popular choice for ballistic armor due to its high strength and low weight, making it an effective material for providing protection to military personnel and law enforcement [6,7].…”

The purpose of this research was to evaluate the Grunwald-Letnikov definition of fractional order derivatives for determining the fractional derivative of ESR signals from UHMWPE free radicals using the fitted Gaussian distribution method. Specifically, the study focused on analyzing two long-lasting oxygen-induced residual radicals di- or tri-enyls with a carbon center radical (R1) and the oxygen-containing radical (R2). The impact of the derivative order on ESR spectral parameters, such as the Landé g-factor and peak-to-peak separation, was analyzed, and new spectral parameters were established for both radicals. The samples were measured in an ESR tube using ESR power saturation techniques at room temperature. Following the measurements, the fitted Gaussian distribution of the ESR signals was used to determine the fractional derivative using the Grunwald-Letnikov definition. Two estimators (I and II) were developed for both radicals, and their values were found to be 9.19 and 4.27 for Radical R1 and 11.51 and 2060.62 for Radical R2. Our results showed that the fractional derivative approach provided accurate and reliable estimations for the radicals. This method can be easily implemented for various ESR signals and can be useful in many applications, including materials science and biomedical research. The accuracy and reliability of our estimators were confirmed by comparing them with the results obtained from the conventional method. Our findings have important implications for materials science and biomedical research, where ESR signals are widely used. This method can help researchers to obtain more accurate and reliable estimations of radicals, which can ultimately lead to more accurate and reliable conclusions in their studies. Additional research is required to assess the effectiveness of this approach on various ESR signals and to investigate its potential use in other fields of study.

“…The finite element method as one of the numerical models is widely intensively used to predict the fretting wear process as it is suitable to solve problems like the non-linearity of boundary conditions, changes in geometry, and the time integration effect, which all happen in fretting wear simulations. Ramírez et al [15] established a finite element model combined with the class Archard's wear law for the prediction of the rate of wear. The accuracy of the modified model was addressed in comparison with experimental results.…”

A tenon connection structure is widely used for the blade-disk connection in turbomachinery, and its ability to resist wear influences operation life. The finite element method (FEM) has been extensively applied in predicting fretting wear due to its advantage in solving problems like the non-linearity of boundary conditions. This work proposes a model that combines a modified Archard model with FEM to simulate fretting wear in multiple pairs of contact curved surfaces of the tenon connection structure. The model considers various factors, including the direction of fretting, time, load magnitude, and the application of aerodynamic load. The results indicate that the direction of fretting has a significant effect on the wear of the tenon connection structure. The wear depth of the tenon connection structure caused by axial fretting is nearly twice that of circumferential and radial fretting, and the corresponding wear depth values are 57.22, 30.85, and 24.36 µm in this study, respectively, and the rate of change in wear depth increases over time, while the contact pressure decreases initially and then increases with continuous wear. This study provides valuable insight into the impact of fretting under different working conditions on the wear of turbine tenon connection structures, which is of great significance for their wear-resistant design and life prediction.
