“…Finite element method (FEM) can incorporate complex anatomical shapes, load scenes, boundary conditions and bone characteristics [6]. These parameters can be examined for their influence on the expected results [7][8][9][10][11][12]. Simulation using finite element (FE) models can provide intuitive graphical results to explain the biomechanics changes after APM [13].…”

Background Recent studies have pointed out that arthroscopy, the commonly-used surgical procedure for meniscal tears, may lead to an elevated risk of knee osteoarthritis (KOA). The biomechanical factors of KOA can be clarified by the biomechanical analysis after arthroscopic partial meniscectomy (APM). This study aimed to elucidate the cartilage stress and meniscus displacement of the tibiofemoral joint under flexion and rotation loads after APM. Methods A detailed finite element model of the knee bone, cartilage, meniscus, and major ligaments was established by combining computed tomography and magnetic resonance images. Vertical load and front load were applied to simulate different knee buckling angles. At the same time, by simulating flexion of different degrees and internal and external rotations, the stresses on tibiofemoral articular cartilage and meniscus displacement were evaluated. Results Generally, the contact stress on both the femoral tibial articular cartilage and the meniscus increased with the increased flexion degree. Moreover, the maximum stress on the tibial plateau gradually moved backward. The maximum position shift value of the lateral meniscus was larger than that of the medial meniscus. Conclusion Our finite element model provides a realistic three-dimensional model to evaluate the influence of different joint range of motion and rotating tibiofemoral joint stress distribution. The decreased displacement of the medial meniscus may explain the higher pressure on the knee components. These characteristics of the medial tibiofemoral joint indicate the potential biomechanical risk of knee degeneration.

“…FEA and CFD have been used in a variety of applications, including metal turning, bone drilling, water jet cutting, and simulations of COVID-19 and other infections. In metal turning, for example, FEA can be used to predict the cutting forces, temperature distribution, and tool wear in a cutting process [6][7][8][9][10][11][12][13][14][15][16][17] . Analytical models can also be used to calculate cutting parameters, as demonstrated by Türkes et al in their research [14] .…”

This paper investigates the effects of tool holder materials on chatter vibration in turning operations. The study uses a complex dynamic turning model with two degrees of freedom for the orthogonal cutting system. Tool holders made from different materials, including Al 5083, Al 6082, Al 7012, and a standard 4140 material, were subjected to chatter vibration to investigate their process damping capabilities. The study found that the standard tool holder 4140 allows for higher stable depths of cut and produces similar process damping values compared to the other tool holders. Finite element analyses (FEA) were performed to verify the experimental results, and the modal and FEA analyses produced very similar results. The study concludes that future research should investigate the effects of tool holders made from high alloy steel alloys on process damping. Overall, this paper provides important insights into the effects of tool holder materials on chatter vibration and process damping in turning operations, which can help in the design of more efficient and effective cutting systems.

“…In many papers in the literature, von-Mises damage criteria were used because meniscus and soft tissues exhibit ductile material properties. In our study, the material properties of epiphyseal plate were selected as cartilage [22,23]. The bone, screws and epiphyseal plate were selected as linear isotropic material in FEA.…”

The biomechanical performance of stainless steel, titanium alloy, cobalt-chromium and NiTi alloy has been compared to fix with parallel fixation in Salter-Harris Type 4 fractures. The best material has been determined under the axial load. 3D model of the parallel fixation has been performed via SolidWorks. Ansys Workbench software was used for numerical analyses. All boundary conditions have defined in finite element analysis (FEA) software. The boundary conditions such as the loading, contact, friction and material model have been determined for FEA. The stress values occurring in the epiphyseal plate of the femur, upper screw and lower screw have been calculated based on von-Mises criteria. At the end of numerical analyses, we have the opinion that, in practice, use of Ti screws in Salter-Harris Type 4 distal femoral fractures will be advantageous.
