Introduction to Dynamics using FEA


January 29th - March 19th, 2018
07:00 PST / 10:00 EST / 15:00 GMT / 16:00 CET
Six Session Online Training Course - 2 hours per session -
one session per week

PLEASE NOTE THAT DAYLIGHT SAVINGS TIME WILL AFFECT  THE TIMING OF SOME OF THE SESSIONS IN THIS COURSE. 
FULL DETAILS WILL BE PROVIDED UPON REGISTRATION.

  • Do you know if your model is realistic?

  • What is the importance of normal modes analysis?

  • How do you calculate transient and frequency response input parameters effectively?

Get the answers to these questions and more with this industry-leading, code-independent e-learning course.


This 6-session, live online course will cover a range of topics, all aimed at structural designers and engineers who are moving into the area of dynamic analysis, including:

  • Normal Modes Analysis
  • Damping
  • Modal Coordinates
  • Modal effective Mass
  • Transient Response
  • Frequency Response

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.


What will you learn?

  • The importance of normal modes analysis
  • Techniques for identifying and characterising normal modes
  • Roadmaps for simple and effective calculation of transient and frequency response input parameters
  • A QA checklist covering normal modes and dynamic response analysis
  • Practical hints and tips on all aspects of normal modes and dynamic response analysis

What questions will this course answer?

  • What are the most important dynamic analysis topics?
  • What theoretical background do I need to understand the implications of my analysis?
  • What practical hints and tips do I need to be able to carry out analysis effectively?

Who should attend?

Designers and engineers who are moving into the area of dynamic analysis. Familiarity with FEA is assumed, but no other background knowledge is required.


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!

This class covers all the FEA solution types required to carry out normal modes and basic frequency response analysis. 



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!



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 @ nafems.org .

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 @ 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.
