An opportunity to ensure that your organisation gets maximum benefit from using FEA
3-Day Training Course - 30th November to 2nd December : Introduction to FEA Analysis
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. Ease of use is generally assured by the software used but there are still many pitfalls and decisions that need to be made in order to obtain a good and accurate answer.
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 engineers get down to the engineering physics behind the problem, with the 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 two-day example-driven, practical course.
Attendees are shown the background to the FEA methodology, via simple real examples with a minimum of theory. The strength and weaknesses of various FEA techniques are shown and discussed and practical considerations of loadings, boundary conditions and structural details are shown via examples.
The assessment, validation and interpretation of FEA results are vital for delivering safe and effective products. These aspects are discussed so that attendees gain confidence in providing conservative, reliable and qualified results. Attendees build this process themselves during a final class activity and come away with an embryo Procedural Check List that should be useful in their own work place. Another class workshop addresses report writing.
The course offers excellent guidance on how to assess and plan the task of carrying out a Finite Element Analysis. A clear understanding of the objectives of each analysis is vital and a road map for achieving this is presented. A review of the trade-off between available resource and analysis methodology is given.
This public course offers important advantages:
This course is aimed at:
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 maybe more suitable and 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.
“Exceeded my initial expectations. I learnt a lot more than I thought I would and it was genuinely interesting.”
“The practical advice given by the lecturer about FEA was very useful”
"Confident to return to work and actually know what I’m talking about!"
"Thank you all for providing this opportunity, I can’t wait to get more experience in the beautiful world of numerical analysis. Special thanks to Gino. You’ve got a crystal clear explanation on your slides."
Registration will be held on Tuesday morning between 9:00am and 09:30am, with the course starting immediately afterwards. The next mornings, the course will start at 9:00am, finishing by 5:00pm approximately.
