This presentation was made at last year's Femap Symposium in Atlanta but it is very relevant to anyone interested in learning about how Femap works with LS-DYNA. The presentation is titled: Femap and LS-DYNA: Rocket Science Made Easy If you would like to see the videos used in this presentation, click on the graphic below and it'll take you to our YouTube video. The next Symposium for us, will be in Seattle. If you would like to register for this Femap and NX Nastran Symposium, just click on the prior highlighted text. We plan on having Mark Sherman out from the Femap Development Team and the usual host of characters to present hard-core technical information on how you can grow and leverage your Femap and NX Nastran skills. Plus, it should be some killer networking and we'll have a no-host bar at the end of the day.

It's nice to know that shipping fixtures have to meet stringent targets for crash, drop and static loading. It would be sort of scary to think of a 3200 kg jet engine breaking lose from its shipping fixture during a 9g crash event and slamming through the bulkhead of a jet liner and into the cockpit. Jet engine stands also have to handle abuse loading due to drops or smashing into walls at 2g loading. Finally, since the complete assembly is often transported over roads, its first natural freqencey needs to be above 10Hz. Historically, these requirements were met by testing and fixture weight was of secondary concern. As we all know, if something is flying, then extra weight is lost revenue. This FEA consulting project took the client's CAD geometry and idealized it down to FEA model that could quickly run implicitly and explicitly using LS-DYNA. The results correlated nicely with the experimental results and indicated that the stand was beautifully designed with little margin left on the table.
This FEA consulting case study brings together various thermal-stress projects we have done over the last decade. If you don't want to see the written version, we have also created a YouTude video on our Thermal-Stress consulting projects that can be viewed here: https://youtu.be/OCXXHL6USd8
