“…According to several numerical studies, higher cup inclination angles result in higher linear wear [58,88,91] due to high contact stress, but lower volumetric wear [18,19,58,127] resulting from reduced contact area (sliding distance), as is in agreement with some hip simulator testing [128,129]. However, higher volumetric wear has been observed with higher inclination angles in other clinical [15], hip simulator [88,130] and FEA modelling studies [91]. Further investigation is hence necessary to understand the difference amongst various FEA, laboratory and clinical studies, especially under the edge loading condition induced by steep cup inclination and lateral separation.…”

“…Almost all of the numerical models on polyethylene liner wear prediction implemented the Archard’s wear law, 85 either in its original form 21–23,46,48,50–54,56–58,61,66,69,86–91 or modified forms, 18,19,25,31,41,49, 60,65,67,68,92,93 mostly in commercial FEA software (e.g. Ansys or Abaqus) by means of user-defined routines.…”

Evaluation and prediction of wear play a key role in product design and material selection of total hip replacements, because wear debris is one of the main causes of loosening and failure. Multifactorial clinical or laboratory studies are high cost and require unfeasible timeframes for implant development. Simulation using finite element methods is an efficient and inexpensive alternative to predict wear and pre-screen various parameters. This article presents a comprehensive literature review of the state-of-the-art finite element modelling techniques that have been applied to evaluate wear in polyethylene hip replacement components. A number of knowledge gaps are identified including the need to develop appropriate wear coefficients and the analysis of daily living activities.

“…Those computational models tried to simulate the stress distribution between the contact surfaces of THA components as functions of the relative displacements performed by each machine. Results suggest that the kinematic and kinetic characteristics directly affect the wear rates, even though a function relating them to the machines' testing parameters could not be established [6][7][8][9][10].…”

“…Therefore, an alternative method, FEM, has been proposed for use across a variety of wear simulations, such as pin-on-plate, 4,11 block-on-ring, 12 brake system, 13,14 and total hip prosthesis in bioengineering. 7,15,16 In FEM wear simulation, Po˜dra and Andersson 4 found that the incremental size may affect the accuracy and stability of the simulation results. Therefore, Ö qvist 5 proposed different incremental sizes to analyze the accuracy and stability of the simulation results.…”

Instead of obsessively emphasizing to reduce the number of time increments and reshape the models, a novel surface contact transformation to increase efficiency is presented in this study. Wear on the bearing surfaces was investigated following the coupled regions from the pressure distribution, computed by means of three-dimensional finite element method models; an approximate analytical model and formulation in three-dimensional frictional contact problems based on modified localized Lagrange multiplier method have also been developed and discussed. Understanding wear behavior patterns in mechanical components is a significant task in engineering design. The proposed approach provides a complete and effective solution to the wear problem in a quasi-dynamic manner. However, expensive computing time is needed in the incremental procedures. In this article, an alternative and efficient finite element approach is introduced to reduce the computation costs of wear prediction. Through the successful verification of wear depth and volume loss of the pin-on-plate, block-on-ring, and metal-on-plastic artificial hip joint wear behaviors, the numerical calculations are shown to be both valid and feasible. Furthermore, the results also show that the central processing unit time required by the proposed method is nearly half that of the previous methods without loss of accuracy.
