Practical, real-world guidance you can rely on.
There are a bewildering array of element types, solution types, meshing methods and pre-post processing options that have to be faced when engineers embark on FEA or companies adopt the technique. This is before engineers even get down to the engineering physics behind the problem, with the associated 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.
Attendees on this course 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, effective products are discussed to provide confidence in the results obtained aiming 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. Report writing is also addressed as a class workshop.
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 course program contains 5 or 6 parts that combine lectures, discussions, workshops and exercises. These may not be provided in the order presented and timing may vary depending on availability.
Practicing engineers who wish to learn more about how to apply finite element techniques to their particular problems in the most effective manner.
Engineers who have started using FEA but have discovered problems and issues (cannot be used as a 'black box'.
Managers (in many cases needing to refresh their knowledge) who review internal or external FEA reports and contract suppliers.
