Composite Finite Element Analysis (FEA)
e-Learning course of 5-sessions; 2.5 hours per session
- Time to take a closer look at Composites FEA?
- Need a clear path through analysis setup and interpretation?
- This course gives you the background for effective FEA
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.
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. Transition to standalone app coming soon.

*Note: While we will make every attempt to follow the course outline, the schedule may be shifted at some point. However, ample notice will be given prior to the start of the course date with regards to the course schedule.
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 w/ microphone) 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 (5+), please send an email to e-learning @ nafems.org in advance for group discounts.
