Practical Introduction to FEA

An opportunity to ensure that your organizationis maximizing the benefits of FEA

3-Day Training Course : Introduction to FEA 

FEA has become widely used and universally accepted in many industry sectors. FEA is a powerful technique, able to produce solutions to challenging structural analysis problems. The technology and computational efficiency of the method, together with the rapid increases in computer processing power means that today the scope and size of simulations far exceeds the capabilities of even a few years ago

However for those engineers embarking on FEA, or companies adopting the technique to improve designs or achieve certification of new products, there is a steep learning curve to overcome.

There are a bewildering array of element types, solution types, meshing methods and pre-post processing options that have to be faced. This is before we get down to the engineering physics behind the problem, with associated classic traps and errors. What is needed is guidance via a thorough but practical assessment of the method and how to use it in the real world. 

NAFEMS, the only vendor neutral, not-for-profit organization with the aim of promoting the effective and reliable use of FEA, addresses this requirement by providing this three day example-driven, practical course.

Students are shown the background to the FEA methodology, via simple real examples with a minimum of theory. The strength and weaknesses of the various FEA techniques are shown and discussed. Practical considerations of loadings, boundary conditions and structural details are shown by numerous examples.

The assessment, validation and interpretation of FEA results are vital for delivering safe, effective products. A process is shown which provides confidence in the results and aims to provide conservative, reliable and qualified results. The attendees join in the activity of building this process themselves and come away with an embryo Procedural Check List

The course offers excellent guidance on how to assess and plan the task of carrying out a structural analysis using FEA. A clear understanding of the objectives of each analysis is vital and a road map for achieving this is presented. A review of the tradeoff between available resource and analy
sis methodology is given.

Interaction is encouraged throughout the course. Real world examples are given at every stage, drawn from the Tutors wide practical experience. Questions are very welcome, as this is one of the key aspects of making this a unique experience for each attendee. Attendee project examples can often be incorporated into the class as time permits, to benefit all. Role playing situations include the class acting as a syndicate to evaluate a Design Failure, critical assessment of an FE Report and the continuous evolution of the Check List.

The course is completely code independent, attendees are welcome to bring laptops to take notes, but they are not required.

A full set of printed and bound notes will be issued to every attendee.

Who Should Attend?

This course is aimed at practicing engineers who wish to learn more about how to apply finite element techniques to their particular problems in the most effective manner. The material that is presented is independent of any particular software package, making it ideally suited to current and potential users of all commercial finite element software systems. This course is a must for all engineers aiming to use FEA as a reliable predictive tool for thermal, stiffness and stress analysis.

Companies moving into FEA technology to improve product designs or assess prototype failures or speed the design process will benefit from sending key engineers to this course. If you have sufficient engineers then a tailor made course may be more suitable. NAFEMS can then work closely with you to cater for your specific industry sector or analysis type.

The course is open to both members and non-members of NAFEMS.
