This paper summarizes the work done to show finite element modeling results on a high temperature superconductor fault current limiter (FCL). The paper also gives the small mock-up design of the matrix FCL and its finite element model (FEM). It also discusses the limitations of the FEM and explains how the results from the FEM compare with the experimental data derived for the configuration. A ...

The SGBEM-FEM alternating method suitable for the solution of elastic and elasticplastic three-dimensional fracture mechanics problems is presented. The crack is modeled by the symmetric Galerkin boundary element method (SGBEM), as a distribution of displacement discontinuities in an infinite medium. The finite element method (FEM) is used for stress analysis of the uncracked finite body. The s...

This paper proposes and analyzes a stabilized finite-volume method FVM for the threedimensional stationary Navier-Stokes equations approximated by the lowest order finite element pairs. The method studies the new stabilized FVM with the relationship between the stabilized FEM FEM and the stabilized FVM under the assumption of the uniqueness condition. The results have three prominent features i...

This paper presents an analysis of the finite element method (FEM) and genetic algorithms for the MEMS analysis and BIOMEMS design. The finite element method is the method used for the computational analysis of mechanical structures in MEMS, BIOMEMS, among others. However, the FEM presents a major drawback: the generation of mesh does not meet any criterion optimization, which in turn prevents ...

The Finite Element Method (FEM) has become the standard tool for the analysis of a wide range of mechanical problems. However, the classical FEM is not well suited for the treatment of large deformation problems since excessive mesh distortions require remeshing. The Material Point Method (MPM) represents an approach in which material points moving through a fixed finite element grid are used t...

A tool for unified simultaneous simulation of multiphysics problems based on Partial Element Equivalent Circuit (PEEC) method is presented. Extension of PEEC method with thermal and mechanical domains is based on circuit interpretation of Finite Difference (FD) and Finite Element Method (FEM) equations. Equations in FEM case are derived by Galerkin's residual method with basis functions of orde...

  In this article, vibration analysis of an Euler-Bernoulli beam resting on a Pasternak-type foundation is studied. The governing equation is solved by using a spectral finite element model (SFEM). The solution involves calculating wave and time responses of the beam. The Fast Fourier Transform function is used for temporal discretization of the governing partial differential equation into a se...

This paper considers the application of numerical techniques to modelling large 3D Extremely Low Frequency (ELF) electromagnetic problems in the time and frequency domains. The environment model consists of three material layers: air, sea and seabed. To represent a coastal region, the sea region is shallow with a variable depth and includes a sloping seabed. The electromagnetic source is a harm...
