Prediction of Occupant Injury in an Out-of-Position Impact Using the Fluid Structure Interaction Capabilities in LS-DYNA
Occupant restraint systems such as seatbelts and airbags are designed to cushion the motion of the occupant when a collision occurs. For an occupant sitting in a normal driving or passenger position, the airbag significantly reduces ...

*MAT GAS MIXTURE, a new gas mixture model for airbag applications
Recent efforts to model fully coupled CFD-airbag processes have motivated the implementation of a gas mixture model in LS-DYNA. The new model, *MAT GAS MIXTURE, allows the mixing of up to eight different gases. It is designed to ...

On Airbag Simulation in LS –DYNA with the use of the Arbitrary Lagrangian - Eulerian Method
In the present paper a basic finite element model of an ALE thorax side airbag with a simplified gas generator will be considered. In particular, it will be discussed how to define boundary conditions and properties of the inflating ...

Application of MADYMO Occupant Models in LS-DYNA/MADYMO Coupling
The LS-DYNA – MADYMO coupling has been extended so that users gain maximal flexibility in their choice of software and models. Where the traditional coupling allowed only MADYMO ellipsoids and planes to contact entities in the coupled ...

Biomechanical analysis of whiplash injuries; women are not scaled down men
Whiplash is the most common soft tissue injury sustained in car accidents. The term is commonly associated with hyperextension of the neck as the head rotates backwards in rear end collisions but the exact injury mechanism is not ...
