Basic Dynamic Finite Element Analysis (FEA)
Five sessions; 2.5 hours per session
Need to refresh your Dynamics skills?
Want to learn how to set up and execute analyses like an expert?
This course gives you practical advice and background.
5-session online training course
Engineering Board PDH Credits: 12.5 hours*
The objective of this course is to break down any Dynamics problem into clearly defined steps and show how to successfully implement practical solutions using Finite Element Analysis.
Dynamic analysis needs a clear set of objectives and analysis plan to:
- Predict what natural frequencies will be important
- Avoid guessing the size or number of time steps in a transient analysis
- Adopt an accurate and logical method to define frequency response calculation points
- Make informed decisions on damping
- Make an engineering assessment – is your model realistic
- Check the answers – guilty until proven innocent!
The nature of Dynamics allows a building block approach to include:
- Normal Modes Analysis
- Modal Coordinates
- Modal effective Mass
- Transient Response
- Frequency Response
Case studies and workshops are carried out in all these areas.
A follow-on course covers Advanced Dynamic analysis concepts.
- Shock Spectra methods
- Random Vibration
- Non-linear Dynamics
Why an e-learning class?
Travel and training budgets are always tight! The e-Learning course has been developed to help you meet your training needs.
If your company has a group of engineers, or specific training requirements across any subjects, please contact us to discuss options.

Feedback from former Dynamic Finite Element Analysis e-Learning students:
"This course did everything right. From organization to presentation to interaction, this is a good model for what online training should be."
"Tony's command over the subject and excellent teaching skills made this course worthwhile."
"Super! Doesn't get better than this. Good idea to start having e-Learning courses."
"I'm really happy not to pay a big fraction of my annual training budget to airlines and hotels. A BIG plus to e-learning."
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.
Review the NAFEMS "Introductory Dynamic FE Analysis " webinar presented by Tony Abbey on April 2nd, 2009.
The purpose of this webinar is to provide some technical content to the NAFEMS community, and to introduce the Dynamic FE Analysis e-Learning course listed on this page.

All sessions are recorded and made available to attendees following the end of the live class. It is perfectly acceptable to attend this class using recordings only.
The course is completely code independent, so is applicable to all FEA users
A full set of PDF notes is available for download. Each session is presented live and is available for review via a streamable recording.
Reading lists, homework submissions, supplementary data are all available for download via the special on-line forum. 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 participation is purely voluntary!
