Time to take a closer look at Composites FEA?
Need a clear path through analysis setup and interpretation?
This 5-session, live online course will cover a range of topics, all aimed at structural designers and engineers.
Composite systems include many more factors than conventional metallic structures.
The objective of this course is to break down the composite analysis process into clearly defined steps, give an overview of the physics involved and show how to successfully implement practical solutions using Finite Element Analysis.
Moving to composite structures will allow you to explore:
Composite materials span:
The challenge for the designer and analyst is to make decisions on the type of idealization and level of detail required in the Finite Element Analysis. Your design may include:
Analysis is further complicated by:
We can help you plan a strategy for dealing with these challenges.
NAFEMS e-learning gives you the best of both worlds, giving you real, practical knowledge that you can use day-to-day to improve your analyses
Note: homework is purely voluntary!
All attendees on the course will be able to download a fully functioning Composite Stiffness and Strength Calculator, together with user guide.
Many past attendees have found this tool a useful supplement to post processing available in their usual Finite Element solution. Attendees will be entitled to future upgrades.
Students will join the audio portion of the meetings by utilizing the VoIP (i.e. headset connected to the computer via headphone and microphone jacks) or by calling into a standard toll line. If you are interested in additional pricing to call-in using a toll-free line, please send an email to: e-learning @ nafems.org .
This is a five-session online training course, with each session lasting for approximately 2.5/3 hours, depending on homework submissions, questions & discussions.
You can attend the sessions live, and/or by listening to the recordings, which will be made available shortly after the end of each session.

*It is your individual responsibility to check whether these e-learning courses satisfy the criteria set-out by your state engineering board. NAFEMS does not guarantee that your individual board will accept these courses for PDH credit, but we believe that the courses comply with regulations in most US states (except Florida, North Carolina, Louisiana, and New York, where providors are required to be pre-approved)
Telephony surcharges may apply for attendees who are located outside of North America, South America and Europe. These surcharges are related to individuals who join the audio portion of the web-meeting by calling in to the provided toll/toll-free teleconferencing lines. We have made a VoIP option available so anyone attending the class can join using a headset (headphones) connected to the computer. There is no associated surcharge to utilize the VoIP option, and is actually encouraged to ensure NAFEMS is able to keep the e-Learning course fees as low as possible. Please send an email to the e-Learning coordinator (e-learning @ nafems.org ) to determine if these surcharges may apply to your specific case.
Just as with a live face-to-face training course, each registration only covers one person. If you plan to register a large group (10+), please send an email to e-learning @ nafems.org in advance for group discounts.
