The following presentation shows a new flexible and efficient methodology to measure material data in the area of static and dynamic behaviour of mechanically loaded products. An impact testing machine including comprehensive ...

A reduction in vehicle side impact deaths continues to be a major focus at NHTSA. In 2002, 23% of crash deaths were attributed to side impact collisions, of which 60% resulted from injuries to the brain. Several significant ...

Many accidents with children or small adults, where the ignition of the airbag leads to dangerous and even fatal injuries for the passengers, have led to a number of efforts to analyze this so-called „Out-ofPosition“ load cases more ...

Using a cockpit system as an example of automotive components, this paper presents how efficiency in product development can be increased by using LS-DYNA explicit / implicit. Concerning the development of these complex and highly ...

Bei Hochgeschwindigkeitsaufschlag auf flüssigkeitsgefüllte Strukturen kann es neben der Schädigung am Aufschlagort selbst durch Ausbreitung von Druckwellen im Fluid auch an weiter entfernten Stellen zu Schäden kommen.

The paper outlines different approaches to fluid-structure interaction modelling in LS-DYNA. Different formulations (Lagrange, Euler, ALE and SPH) are evaluated and compared with experimental observations of a fluid sloshing problem ...

After the discussion of aspects of Smoothed Particle Hydrodynamics the SPH method in LS-DYNA is presented.

This talk gives an overview of LS-DYNA-EFG including the implementation and examples of industrial applications. Further on, the recent developments of LS-DYNA-EFG are discussed which includes the inclusion of different EFG background ...

This talk introduces FE experiments with varied parameters and gives a brief analysis of the results.

Most of the modern simulation techniques require a mesh on which the mathematical model, describing the physical process, is discretized. It could be a volume mesh for a CFD analysis or a surface mesh for structural investigations. ...
