| Crashworthiness and Occupant Safety deal with the structural integrity of a vehicle during impact, especially as it relates to the safety of its passengers. LS-DYNA is widely used by the automotive industry to analyze airbags, structural components, crash-test dummies and the interactions of all of these during an impact in order to assess the crashworthiness of a vehicle. LS-DYNA was built to handle the large deformations, sophisticated material models, and complex contact interactions required to analyze vehicle crash simulations. The material models used by LS-DYNA for this analysis include steel and aluminum, rubbers, foams, plastics, and composites. Additionally, LS-DYNA handles the complex contact conditions among multiple components and short-duration impact dynamics. LS-DYNA is used for all crash events: frontal impact, side impact, rear impact, and rollover.
