10 Steps to Successful Explicit Dynamic Analysis

September 17th & 24th 2018
07:00 PDT / 10:00 EDT / 15:00 BST / 16:00 CEST
Two-Session Live Online Training Course - 2-2.5 hours per session
Attend the live sessions, or view the recordings at your convenience



  • When can I use explicit dynamics?
  • What is hourglassing?
  • How can I speed up my analysis?

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

Explicit dynamics is simple, right? It’s easy to set-up the model, and the software takes care of the rest. But what happens if something goes wrong? If the computer time is way off the charts? And even if you do eventually get to a solution, is it as accurate and robust as it could be?

This 2-session, live online course will cover the theoretical background of explicit dynamics (briefly!), the advantages and limitations, approaches to speed up the solution, select elements, material modelling, modelling contact boundaries, typical results and the specific simulation considerations, as well as showing real-world industrial examples including manufacturing, impact, explosion, and many others.

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 uniqueness of explicit dynamics
  • Limitations of explicit dynamics
  • What hourglassing is and how to control it
  • How to do mass scaling

What questions will this course answer?

  • When can I use explicit dynamics?
  • What is hourglassing?
  • How can I speed up my analysis?

Who should attend?

  • Engineers and Managers wishing to use explicit dynamics themselves or within their departments. This is often the first step into the nonlinearity and time-dependent area after linear static analyses that is often problematic due to the specific issues related to explicit dynamics.
  • Engineers should be familiar with dynamic behaviour, contact, large deformations, etc. that are referred to in the course but not dealt with in any detail.

Specialised design problems involving short-duration high-pressure loadings generally require the use of explicit dynamics methods to obtain a good answer within reasonable timescales. These problems often simulate severe loading and material failure, from events such as impact, blast loading, car crash, etc. 

Some manufacturing simulations in which there is changing contact between components with the material undergoing vast deformation also use explicit dynamics methods, such as metal forging, sheet metal pressing, etc. Proving the necessary inputs and checking the results is important but often the real source of errors encountered in the simulation is difficult to determine. 

This course provides a basic overview of explicit dynamic simulation methods, briefly describing the theoretical nature together with its software implementation and its advantages and disadvantages.

It should help engineers carry out explicit dynamics simulations, ensuring accurate and robust solutions with correct analysis choices avoiding possible pitfalls. It should also help engineers distinguish problems that should be solved explicitly or implicitly, thereby providing the least time to obtain a solution.

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 @ .

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.

Engineering Board PDH Credits

*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).
