“…Although the wear submodeling procedure proved to be an efficient solution to the high computational cost problem, as also confirmed by Shankar et al, 9,10 the main limitation of the previous study was that the discussion was restricted to a SPC case. The extension of the technique to a more general three-dimensional and multipoint contact (MPC) case is obviously of great importance.…”

The application of the submodeling technique to finite element (FE) wear analyses has been recently proposed as an efficient solution to reduce the computational cost of the simulations and provide accurate numerical results.However, the method was validated only on single point contact cases. The present study proposes a generalization of the wear submodeling procedure that can be used to speed up FE wear simulations with multipoint contacts. The modified global-local procedure is applied and evaluated on a double contact pin on plate wear test using three-dimensional models developed in Ansys® mechanical APDL. Three different model geometries with different curvature radii at the contact regions were considered in order to replicate possible critical scenarios. Results suggest that an additional wear simulation step where the global model is used to simulate the first wear cycles is needed to correctly transfer the boundary conditions to the local models. The new proposed strategy demonstrates the possibility to extend the method to more general FE wear simulations by significantly reducing their computational cost.

“…Based on the peak load of 3000 N for gait motion in the ISO 14242 standard, the load per unit area of the acetabulum is calculated to be about 4.05 N/mm 2 , assuming an initial contact area of 1 mm 2 for the ball-disk sample and choosing a safety factor of 3, 33 according to equation (1). Where K is the safety factor, according to existing studies, 34 the gait activity load of the hip joint is higher in actual human gait activity, so in some current theoretical test load conversions, 35,36 it often needs to be scaled up so that it is more similar to the actual human hip joint load. P is the unit bearing, S is the contact area, and the obtained ball-disk interface load is about 12.15 N. To simplify the calculation, an approximate value of 10 N is taken.…”

“…P is the unit bearing, S is the contact area, and the obtained ball-disk interface load is about 12.15 N. To simplify the calculation, an approximate value of 10 N is taken. Also referring to the study of Shankar et al, 35 20 N and 30 N were selected as the other two sets of test loads, respectively, considering the larger body weight loads and a series of daily human movements (running, carrying, going up and down stairs, etc.). The samples were ultrasonically cleaned in anhydrous ethanol for 20 min before the test was carried out, then dried for 20 min using a constant temperature drying oven (DZF-1, Beijing Zhongxing Weiye Century Instruments Co., Ltd.), and finally weighed 5 times using an electronic balance (JM-B2002 type, Zhuji Chaoze Weighing Equipment Co., Ltd.) (the average value was taken after rounding off the maximum and minimum values).…”

In order to investigate the effect of frictional heat on the wear resistance characteristics of polymeric acetabular materials, the tribological tests and wear numerical analysis of three common polymer acetabular materials were carried out under different synovial fluid temperatures. The study results show that XLPE and VE-XLPE exhibit superior wear resistance compared to UHMWPE in high-temperature, heavy load environments. The coefficient of friction of three materials gradually decreases as the temperature of the synovial fluid increases. The wear depth and wear volume of the three materials increased with the increase of the temperature of the synovial fluid, and the forms of wear at 46°C and 55°C were mainly adhesive wear and plastic deformation. The higher temperature of the synovial fluid accelerates the oxidative degradation of the material surface and generates oxidation functional groups, which leads to the breakage of C-C bonds in the surface molecular chains under the sliding shear effect, thus reducing the mechanical properties of the material. Specifically, the surface of the polymer material will soften at a higher ambient temperature, mainly due to the decrease of hardness, and then deteriorate in the friction property, and finally increase the wear rate. Ansys results showed that the volume wear of the three materials increased with the increase of synovial fluid temperature, and the trend could be approximately linear. Numerical calculations predict that VE-XLPE has the highest wear of 0.693 mm3 among the three materials at 37°C, followed by XLPE at 0.568 mm3 and UHMWPE with the lowest wear of 0.478 mm3. At higher synovial fluid temperatures (46°C, 55°C), VE-XLPE still has the largest wear volume among the three materials, while XLPE and UHMWPE have similar wear. The wear cloud pictures showed that the maximum wear volume occurred near the edge of the acetabulum.

“…Many factors affect the wear behavior, and the influence of the influencing factors on the wear is often not a single effect; there is an interaction between the influencing factors. Using total hip arthroplasty (THA) as an example, Shankar et al [26,27] applied this method to study the contact pressure and wear in hip joint prostheses made of metal, ceramic, and polycrystalline diamond materials, as well as the wear behavior of silicon nitride and Ti6Al4V alloy under the influence of five different biological lubricants during various gait activities. Prasad and Ramkumar [28] employed the sub-model method to investigate the wear performance of ceramic hip joint implants under dynamic edge loading conditions.…”
