Essentials for Finite Element Simulation
2014Finite Element (FE) simulation solves the mathematical model of the physical problem. The following sections discuss the essential elements for the FE simulation process with respect to an illustrative problem in the assessment of solder joint reliability.

Finite Element Simulations of Twisted NbTi Conductors
IEEE Transactions on Applied Superconductivity, 2013Low-temperature superconducting wires, NbTi and Nb3Sn, designed for ac applications, such as CERN and ITER magnets, are composed of twisted multifilament structures. Under time-varying applied magnetic field, twisting decreases the induced electromotive forces between the filaments and is therefore an effective method to reduce interfilamentary ...

Finite-element simulation of solidification
Journal of Materials Processing Technology, 1990Abstract The problem of predicting the solidification front and the temperature field for the case of the continuous-casting process is of great practical importance. Due to the release of latent heat during the change of phase, such a problem is non-linear and considerably more difficult to solve than the corresponding single-phase problem.

Presurgical finite element simulation of scoliosis correction
Journal of Biomedical Engineering, 1989For surgical correction of scoliotic spinal deformity, internal fixation systems apply lateral and distractive corrective forces. In order to gain maximal correction, a finite--element analysis of the spinal deformity correction technique has been carried out preoperatively, after first employing the spinal deformity correction finite--element model to

IMPACT SIMULATIONS USING SMOOTHED FINITE ELEMENT METHOD
International Journal of Computational Methods, 2013We present impact simulations with the Smoothed Finite Element Method (SFEM). Therefore, we develop the SFEM in the context of explicit dynamic applications based on diagonalized mass matrix. Since SFEM is not based on the isoparametric concept and is based on line integration rather than domain integration, it is very promising for events involving ...

Finite-Element Simulations of Earthquakes
2000This thesis discusses simulations of earthquake ground motions using prescribed ruptures and dynamic failure. Introducing sliding degrees of freedom led to an innovative technique for numerical modeling of earthquake sources. This technique allows efficient implementation of both prescribed ruptures and dynamic failure on an arbitrarily oriented fault ...

3D finite element simulation of Cotrel-Dubousset correction
Computer Aided Surgery, 2004The Cotrel-Dubousset (CD) scoliosis surgery was simulated for 10 patients with idiopathic scoliosis using a 3D finite element model (FEM) of the patient's entire spine. The geometry of the FEM was extracted from a 3D stereo-radiographic reconstruction, and mechanical properties were personalized using lateral bending films. Finally, each step of the CD

Time-Domain Finite Element Simulation of Conductive Regions
Digest of the Fifth Biennial IEEE Conference on Electromagnetic Field Computation, 1993Transient magnetic fields are analyzed in the time domain by using the finite-element method (FEM) in space and the finite-difference method in time. Conductive regions are eliminated from the domain under examination by imposing impedance boundary conditions on the surfaces separating conductive and nonconductive regions.
