Numerical Simulation of Free-Air Explosion Using LS-DYNA
Applied Mechanics and Materials, 2014The development of advanced computational technologies in recent years has seen studies of the effects of explosions on large structures becoming feasible and, as a consequence, the number of destructive tests and their high cost can be reduced significantly.

Computer Simulation for Building Implosion Using LS-DYNA
2011A complex simulation of the demolition of a high-rise building in Hagen is presented. This building because of its geometry (approx. 100m height) and of the applied blasting strategy (resulting in vertical collapse) was impossible to be computed with a simple fracture algorithm modelling the local failure mechanism.

Simulating Neck Injury in Frontal Impact using LS-DYNA
SAE Technical Paper Series, 2007<div class="htmlview paragraph">Neck injury assessment is part of the FMVSS208 requirements. Hardware tests are often conducted to validate whether the vehicle safety system meets the requirements. This paper presents a full vehicle finite element model using LS-DYNA, including structural components, restraint system components, and dummies.

Numerical Simulation of Dynamic Compaction Using Ls-Dyna
2009In the process of dynamic compaction, large deformation occurs at some rammed points and their surrounding areas. In this paper, the vibration of dynamic compaction is analyzed with the large deformation theory and LS-DYNA finite element software is employed to simulation the process of dynamic compaction.

The Masonry Crack Propagation Simulation Based on LS-DYNA
Advanced Materials Research, 2014Due to the development of the computer hardware and the difficulties in determining the constitutive relation, it is difficult to research the crack propagation of large-scale masonry with the finite elements analysis method. The paper analyses the single storey concrete block masonry experimental model with the software LS-DYNA, using winfrith ...

Manual interface LS-Dyna and MATLAB
2010The goal of this manual is to give an introduction to build a data interface between the finite elements software LS-Dyna and the numerical computing environment MATLAB. A case study is used to illustrate the working principle of this interface. In this case study the dynamic behaviour of aluminium plates subjected to close range blast loads is ...

Validating FSI Simulations in LS-DYNA 971 R7
The latest release of LS-DYNA includes a multi-physics solver that combines computational fluid dynamics and structural solvers. This capability is a new computational design tool for the automotive industry. One of the simplest ways to reduce weight and increase fuel efficiency is to trim unnecessary weight from the body panels which comprise the ...Kevin A. Gardner +2 more

Fluid Structure Interaction Parachute Benchmark Models in LS-DYNA
AIAA Aerodynamic Decelerator Systems (ADS) Conference, 2013This paper describes the development and results of numerical models describing system level parachute performance. The numerical models were developed to replicate a series of parachute drop tests conducted in the early 1950s. Wright Air Development Division Report AFTR 5867 documents 700 parachute drop tests, using twenty seven different parachutes ...
