Many engineers see LS-DYNA as the ‘industry standard’ 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).
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).
So when does it make sense for engineers to use an explicit dynamics approach? An explicit dynamics solver is the best approach for simulating short duration transient events, often characterised by one or more of these features:
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.
Examples of applications where LS-DYNA excels can be seen in many industries including Civil, Automotive & Defence:
Civil
Applications include Dams/soil interaction & earthquake structural response:
Automotive crash and roadside barriers:
Defence
Blast and Impacts, as well as complex parachute deployment:
Other dynamic or complex non-linear events:
Rail
Derail and impact: learn more about the example below at this detailed blog on the simulations conducted following the Waterfall train disaster.
Regardless of whether you’re new to Explicit Dynamics simulations or an industry veteran, we highly recommend you take advantage of the 2020 LS-Dyna Virtual user conference – all presentations are now available online and on-demand: you can access them via this link: https://www.ansys.com/other/lsdyna-conference/agenda
Do you have your own challenging engineering problem to solve that involves a short-duration, transient event such as an impact, crash, blast or drop test? Get in touch with the experts at LEAP today to see how you can get started with explicit dynamics simulation!
