As a new choice for the treatment of degenerative lumbar disease, artificial lumbar disc replacement has been widely used in clinical surgery. The finite element is a very effective method to predict and simulate the surgery effect. The purpose of this paper is to review the applications of finite element in artificial lumbar disc replacement, such as design of artificial lumbar disc prosthesis...

The present review paper has several objectives. Its primary aim is to give an idea of the general features virtual element methods (VEMs), which were introduced about a decade ago in field numerical for partial differential equations, order allow decompositions computational domain into polygons or polyhedra very shape. Nonetheless, also addressed readers who have already heard (and possibly r...

Analysis of a variety of dynamic phenomena requires simultaneous resolution at both atomistic and continuum length scales. A combined molecular dynamics and finite element method approach, which we discuss in this paper, allows us to find the balance between the necessary level of detail and computational cost. The combined method is applied to the propagation of a laser-induced pressure wave i...

The article presents the methodology for finding material damping properties at higher frequency and at relatively lower amplitudes. The method employs combined Finite element and frequency response for finding the damping characteristics of composite materials, which are used in high frequency applications. The hybrid method has been implemented on carbon fiber reinforced polymer (CFRP) and gl...

The combined field integral equation method is used to calculate the RF B1 field produced by a transmission line resonator element for high field magnetic resonance systems. The proposed method provides faster electromagnetic field results than the finite difference time domain approach. A field localization method is also discussed.

A hybrid combined finite element–finite volume method has been developed for the numerical simulation of shear-dependent viscoelastic flow problems governed by a generalized Oldroyd-B model with a non-constant viscosity function. The method is applied to the 4:1 planar contraction benchmark problem, to investigate the influence of the viscosity effects on the flow and results are compared with ...

Even in homogenous soil and for simple geometrical structure the analytical design of a grounding system is a complex and not very accurate procedure. Using Finite Element Analysis (FEA) it can perform a precise design for complex grounding systems but with important hardware resources and time consumption. This paper proposes a methodology for power system grounding design, directed to ensure ...

Erecting shield wires is one of the effective measures to improve power frequency electric field environment around high voltage transmission line, which can reduce the impact of power frequency electric field to surroundings and human activity. There is an unknown multidimensional non-linear relationship among the quantity of shield wires, the suspended positions and shielding effectiveness. T...

This paper describes a numerical solution for two dimensional partial differential equations modeling (or arising from) a fluid flow and transport phenomena. The diffusion equation is discretized by the mixed hybrid finite element method. The saturation equation is solved by a finite volume method. We start with incompressible single-phase flow and move step-bystep to the black-oil model and co...
