Fluid-Structure Interaction in LS-DYNA: Industrial Applications

Emerging Technology in Fluids, Structures, and Fluid Structure Interactions, 2002
A new Fluid Sructure coulping algorithms basesd on the penalty method is dpresented in thi spaper. The coupling algorithm and improved multi-material ALE-capabilities have made LS-DYNA an efficient tool for analyzing large deformation processes, such as bird strike events, forging operations and penetration problems and airbag simumations.

Multiphase and Chemically Reactive Flows in LS-DYNA

21st AIAA Computational Fluid Dynamics Conference, 2013
We have developed a transient multiphase fluid dynamics and chemically reactive flow simulation capability in conjunction with the existing LS-DYNA FEM structure solver, which is a well-known general-purpose highly nonlinear, transient dynamic finite element software capable of simulating complex real world problems, and is widely used in automobile ...

Simulation of the Childbirth Process in ls-dyna

Journal of Biomechanical Engineering
Abstract Childbirth or labor, as the final phase of a pregnancy, is a biomechanical process that delivers the fetus from the uterus. It mainly involves two important biological structures in the mother, the uterus—generating the pushing force on the fetus—and the pelvis (bony pelvis and pelvic floor muscles)—resisting the movement of the

LS‐DYNA and the 8:1 differentially heated cavity

International Journal for Numerical Methods in Fluids, 2001
AbstractThis paper presents results computed using LS‐DYNA's new incompressible flow solver for a differentially heated cavity with an 8:1 aspect ratio at a slightly super‐critical Rayleigh number. Three Galerkin‐based solution methods are applied to the 8:1 thermal cavity on a sequence of four grids.

ALE and Fluid/Structure Interaction in LS-DYNA

Emerging Technology in Fluids, Structures, and Fluid Structure Interactions: Volume 1, Fluid Dynamics and Fluid Structure Interactions, 2004
Fluid-structure interactions play an important role in many different types of real-world situations and industrial applications involving large structural deformation and material or geometric nonlinearities. Numerical problems due to element distortions limit the applicability of a Lagrangian description of motion when modeling large deformation ...

LS-DYNA Simulation Influence on Roadside Hardware

Transportation Research Record: Journal of the Transportation Research Board, 2004
Several new roadside safety appurtenances that can be directly linked to the use of nonlinear finite element analysis with LS-DYNA are being installed along the nation's roadways. These advances can be attributed to FHWA's sponsored research program known as Centers of Excellence in DYNA3D Analysis.

Integration of LS-DYNA in the Process Chain of an Automotive Manufacturer

2004
The introduction and evaluation of the simulation tool LS-DYNA in manufacturing process simulation is the basis for a new view in the virtual development chain. The explicit LS-DYNA forming simulation can map complex processes very exactly. One intention is to achieve more accurate computer models with the transfer of the part properties caused by ...

High Explosive Impact Analysis Using LS-DYNA

Emerging Technology in Fluids, Structures, and Fluid Structure Interactions, 2003
In order to realize numerical simulation of fast transient events, some wave propagation codes, which allow studying the time resolved development of shock wave propagation due to penetration, and detonation, were developed. In this article, Eulerian Multi-material and Arbitrary Lagrangian Eulerian formulations are used.
