  • Time to take a closer look at Composites FEA?

  • Need a clear path through analysis setup and interpretation?

This industry-leading, code-independent e-learning course gives you the background for effective FEA.

This 5-session, live online course will cover a range of topics, all aimed at structural designers and engineers.

You can either attend the live sessions or
take the course on-demand at your leisure. 

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.

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: 

  • increased structural strength and stiffness to weight ratios
  • simpler manufacturing processes
  • more innovative design capabilities 

Composite materials span: 

  • cheap and freely available glass fiber reinforced systems
  • exotic and tailored carbon, boron or Kevlar systems
  • many other fiber and matrix systems

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: 

  • thick composite sections with large numbers of plies
  • regions of significant ply drop off
  • tee joints loaded in tension
  • structural shapes causing changes in draping angle or thickness

Analysis is further complicated by:

  • a wide range of failure theories
  • large amounts of stress and strain data for each ply 

We can help you plan a strategy for dealing with these challenges.

The course is completely code independent.

  • A full set of notes in PDF format will be available for download. Each session is presented live and is available for review via a streamable recording.

  • Personal passwords are provided to allow you to access e-learning backup material via our special bulletin board. Reading lists, homework submissions, supplementary data are all stored as files on the bulletin board.

  • Interaction via the bulletin board is strongly encouraged to obtain the most from the e-learning class. Typically the board runs for 4 weeks after the last live class sessions, giving you plenty of time to catch up with homework, review and ask questions.

Note: homework is purely voluntary!

Free Composite Stiffness and Strength Calculator

All attendees on the course will be able to download a fully functioning Composite Stiffness and Strength Calculator, together with user guide.

  • Carry out the homework tasks
  • Explore composite layup stiffness and strength 
  • Calculate Failure Index and Strength Ratios 
  • Display ABD matrices
  • View full details of calculation ply by ply

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.

Course Process and Details 

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 @ .

Course Program

This is a five-session online training course, with each session lasting for approximately 2.5/3 hours, depending on homework submissions, questions & discussions.

Special Note(s):

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 @ ) 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 @ in advance for group discounts.
