Die neuen Fussgaengerschutz(FGS)-Kriterien, welche in Form der ACEA Selbstverpflichtung ab Mitte 2005 zur Anwendung kommen, erzwingen fuer ihre Umsetzung Deformationszonen an der Fahrzeugfront. Speziell im Bereich der Motorhaube ...

New regulations and consumer tests for passive safety in passenger cars have increased the demand on accurate models for occupant analysis. Thus, effects that have been neglected or modeled rather coarsely in recent occupant models ...

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 ...
