Many engineers see LS-DYNA as the \u2018industry standard\u2019 for automotive & crash applications, including vehicle crash safety assessment, impacts with roadside furniture, roll-over protection, car seat design and also for general drop tests (particularly for consumer electronics).<\/p>

But did you also know that the solver within LS-DYNA is incredibly capable and can also be used in many other areas, including blasts relevant to defence, aerospace impacts such as bird strikes on jet engines, crash safety for robotics & unmanned vehicles, drilling\/cutting operations, metal forming, sports & safety equipment, as well as civil engineering applications including demolition or complex structure-soil interaction (such as those involving foundations and dams).<\/p>

So when does it make sense for engineers to use an explicit dynamics approach?\u00a0 An explicit dynamics solver is the best approach for simulating short duration transient events, often characterised by one or more of these features:<\/p>

\u2022 Short-duration, complex or changing\u00a0body interactions with complex contacts<\/div>
\u2022\u00a0Impact up to hypervelocity<\/div>
\u2022\u00a0Severe loadings resulting in large material deformations eg. stamping and forming<\/div>
\u2022 Material failure & fragmentation \/ catastrophic failure eg. blade containment following bird strike<\/div>
\u2022 Impact Penetration<\/div>
\u2022\u00a0Blast-structure interaction<\/div>

After a long-standing decades-long partnership, more recently Ansys acquired Livermore Software Technologies Corp (LSTC) to bring together the powerful combination of Ansys Workbench and LS-DYNA. If you have a challenging engineering simulation problem on the horizon, then LEAP has the team and the tools to help you solve it.<\/p>

Examples of applications where LS-DYNA excels can be seen in many industries including Civil, Automotive & Defence:<\/p>
