A car crashes, what impact will the airbags have on the driver?
LS-DYNA LSTC (Livermore Software Technology Corp) is a world leader in explicit simulation technology. The time tested nonlinear transient dynamics FEA solver with explicit time integration has been the industry standard since 1996. This software offers the most cutting edge explicit solver technology, and along with its wide range of contact algorithms and rich material database, LS-DYNA enables the user to simulate sophisticated explicit dynamic systems with high fidelity and ease.
What is an explicit dynamics simulation?
An explicit dynamics system is an environment where large structural deformation, coupled with high intensity loading are present in a short time frame. Such environment is typically present during structural impact and catastrophic failure. In the past these cases have been simulated with physical testing, however, not every case can be physically simulated due to scale, precision, cost as well as other factors (For example mid air collision or earth quake). Hence in the fast pace, highly competitive engineering industry of today, the demand for a cost effective, accurate, and robust explicit dynamics simulation tool has never been stronger.
Where does LS-DYNA fit in?
LS-DYNA LSTC excels at simulating short duration, high intensity loading scenario between solid to solid dynamic interaction, and with their comprehensive set of contact types, along with its fast solution processing. Simulating explicit dynamics has never been easier.

LS-DYNA in the Australian engineering industry
Connell Wager (now Aurecon) used LS-DYNA to conduct crash worthiness study of highway road barriers against oblique impact from a 36 tonne truck at 80km/h. Typically, impact testing in a lab environment would not be able to simulate the impact behaviour with enough precision, while live testing could be too costly.
The analysis took advantage of the sophisticated material models in LS-DYNA database and was able to thoroughly examine the effect of strain rate behaviour of the barrier on the impact results. The results from the simulation identified several weaknesses in the barrier design that would of compromised the structural integrity of the barrier, and thanks to the LS-DYNA simulation, the final design was improved before the commencement of production.
