Presurgical finite element simulation of scoliosis correction

Journal of Biomedical Engineering, 1989
For 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

Manufacturing Simulation Using Finite Element

2012
Using nonlinear finite element method to simulate the manufacturing process can help to optimize its design parameters and produce better parts. The main topics discussed in this chapter are riveting, shot peening, and material removal (end mill).

IMPACT SIMULATIONS USING SMOOTHED FINITE ELEMENT METHOD

International Journal of Computational Methods, 2013
We 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-Elemente-Simulation kleiner Nachhallräume

ATZ - Automobiltechnische Zeitschrift, 2011
Der Diffusfeld-Absorptionsgrad (Diffuse Field Absorption Coeffizient, DFAC) ist eine physikalische Groesse, mit deren Hilfe in der Automobilindustrie haeufig die Leistung schalldaempfender Teile bewertet wird. Fuer Experimente in diesem Zusammenhang nutzen Automobilhersteller und Innenausstatter bislang so genannte Alpha-Kabinen.

Finite-Element Simulations of Earthquakes

2000
This 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, 2004
The 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, 1993
Transient 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.

Finite Element Compositional Reservoir Simulation

SPE Annual Technical Conference and Exhibition
Abstract We develop a fully coupled phase-field compositional simulator using an enriched Galerkin (EG) discretization to address key limitations of traditional sequential-implicit workflows in multiphase, multicomponent reservoir simulation. The phase-field framework replaces conventional flash calculations and capillary pressure tables

Fast Finite Element Modeling for Surgical Simulation

1999
Given the geometric complexity of anatomical structures, realistic real-time deformation of graphical reconstructions is prohibitively computationally intensive. Instead, real-time deformation of virtual anatomy is roughly approximated through simpler methodologies.
