Optimization and the Impact of Various Factors on the Orthopedic Cement Used in the Total Hip Arthroplasty

Journal of biomimetics, biomaterials and biomedical engineering (2023)

The aim of the present investigation is to determine the ideal values for several parameters, such as the external diameter of the polyethylene liner, the Young's modulus of the cup, and the friction coefficients between the polyethylene liner's contact area and the acetabular shell and prosthetic head of the dual-mobility cup. Reduced stresses at the bone/cement interface are crucial for ensuring a well-fixed dual-mobility cup (DMC) with the acetabulum because orthopedic cement (PMMA) is the weakest component of total hip arthroplasty (THA). Four factors, such as the PE liner size, the rigidity of the cup, and the friction coefficients, are optimized using the three-dimensional finite element method (FEM) and experimental design approach (EDA). The numerical results show that the hemispherical-liner size, mechanical characteristics of the cup, surface state of the femoral head, liner PE, and shell components all influence the mechanical strength of the bone cement. To prevent fracturing the bone cement, which would render the total hip arthroplasty ineffective. The optimal values of the maximum von Mises stress in bone cement will be determined using this methodology. The numerical outcome shows that when the Young's modulus of the cup rises, the maximum stress in bone cement falls until it reaches a minimal value. The maximum stress in bone cement, however, increases as the PE liner's exterior diameter increases. Because the maximum stress is still below the yield stress of bone cement, the artificial hip joint is still considered safe despite the increased stress value.

Prediction of mechanical behavior of friction stir welded joints of AA3003 aluminum alloy

Frattura ed Integrità Strutturale (2020)

Ismail Chekalil Abdelkader Miloudi Marie-Pierre Planche Abdelkader Ghazi

Friction stir welding (FSW) is an extremely complex process because it depends on the intrinsic and extrinsic factors of the material under consideration. The purpose of the present work is to formulate a set of recommendations concerning the choice of the different factors that are likely to influence the quality of the FSW joint and to find a mathematical model that allows predicting the mechanical behavior of the junction. An experimental design was therefore used to highlight the effect of the welding parameters on the behavior of the aluminum alloy FS-Welded joint. The most influential parameters were shown to be in the order of rotational speed, feed rate and tool tilt angle. The study of the interactions between these different parameters made it possible to establish a number of combinations of the different factors for the purpose of achieving the quality optimization of the FSW joint by obtaining a tensile strength of the weld joint equal to of that of the base metal.

Corrosion Behavior of Aa3003 Friction Stir Welded Joints

Ismail Chekalil Abdelkader Miloudi Abdelkader Ghazi Redouane Chadli Marie Pierre Planche

This work focuses on the corrosion behavior of the friction stir welded joint of aluminum alloy 3003. In order to quantify the quality of FSW joints, the corrosion in the welded joint and the base metal was compared. A gravimetric and thermodynamic study was carried out to determine corrosion resistance. Three aggressive media based on three solutions (sodium chloride, hydrogen chloride, and ethylene glycol) at four temperatures (25°, 45°, 65°, and 85°C) were tested. The results showed that temperature has a strong influence on corrosion rates, which are higher in the metal than in the FSW joint. The presence of ethylene glycol considerably reduces the rate of corrosion, its effect is more marked on the FSW joint. The adsorption of ethylene glycol on the surface of the base metal and that of the FSW joint follows the Langmuir isotherm to form a monolayer on the surface of both samples.
