Another Femap and NX Nastran Class "In-the-Can"

Predictive Engineering finishes another Femap and NX Class at their office in Portland, OR. Students attended from Honda Aerospace, Endeavor Analysis, Boeing, Greenbrier Rail, Sierra Nevada Corporation and Moog CSA Engineering.

In the instructor feedback review, this review says: "Adrian is very knowledgable about the finite element process and Femap. Always had answers to questions and workshops were very good. Enough repetitiveness to help learn functions but not so much to make it monotonous. Much respect for Adrian." The overall scoring was silly high with only one "4" and the rest 5's. As the original developer of the class (me), I never got such high scores! Which has me thinking that I'll have to work to make the next class more challenging for the students such that the marks aren't quite as high.

We'll be having another Femap training session the week of October 19-23, please click the link for registration information, or contact us if you or your team needs training!

Predictive Engineering Thermal-Stress Consulting Experience

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

In the case study you'll find an onsite synopsis, a short summary video, and a PDF case study of the following thermal-stress projects that we have done using Femap, NX Nastran and LS-DYNA:

  1. Thermal-Stress Analysis of 500kW Generator
  2. Thermal-Deflection Analysis of Composite Fabrication Mandrel
  3. Thermal-Stress Analysis of Hydrogen Reactor
  4. Thermal-Stress Analysis of Potted DC-AC Invertor and other Electronic Devices
  5. ASME Thermal-Stress Analysis of Thick-Walled LOX and RP1 Propellant Tanks
  6. Thermal-Stress Effects within Thick Composite Laminate
  7. Thermal-Stress Analysis of Water Cooled Stoker Grate
  8. Overview of General Thermal-Stress Projects

Engineering Simulation of Friction Stir Welding

Most major aircraft manufacturers use friction-stir welding (FSW) to join aluminum parts. The trick is that the aluminum never reaches its melting point and hence prevents typical solidification defects found in fusion type welding.

One of our Predictive Engineering engineers worked to develop a simulation package that can model the weld process using smoothed particle hydrodynamics on the graphical processing unit (GPU). The simulation code allows the engineer to predict joint efficiency, cleanliness (minimal defects) as well as residual stresses and deformations. That quick simulation is a huge advantage for our FSW-using clients. See our simulation video below, or at https://youtu.be/knrbYckgmqg
