I have been providing e-learning courses on FEA for over 11 years. I now supplement the courses with a free weekly broadcast that covers topics across FEA. Format – live presentation around 30 minutes. Q and A 30 minutes . Completed presentation recordings to view Session 1. St Venant’s Principle […]
Gimme a ticket for an aer-o-plane
Have you heard the 1967 hit from the Box Tops, released later by Joe Cocker? Gimme a ticket for an aer-o-plane Ain’t got time to take a fast train Lonely days are gone, I’m a-goin’ home ….. Ok, that dates me – but check it out, it’s a great song. I should have subtitled this […]
Plane Stress and Plane Strain – simplifying models
Background A previous article explained that even with powerful modern computers, there is often a motivation to use simplifying techniques in Structural FE Analysis. This follow-on article describes how two closely related methods can be used to take 2D slices through a complex structure at regions of interest. The resulting FEA models can give valuable […]
Session 13: FEA models under or over constrained!
Video : 60 minutes presentation and curated Q and A Over-constrained, under-constrained or somewhere in the middle with FEA! Boundary conditions are probably the most difficult aspect of static FEA Underconstrained models: It is easy to forget to apply adequate constraints – Rigid Body Modes result! Over constraining is more subtle: The physics of the […]
Session 12: Can Designers really take advantage of FEA?
Video : 60 minutes presentation and curated Q and A Given a design, the big question is, who will carry out the FE analysis If it is the designer: Is it more efficient to do this within a CAD embedded environment, or divert the task to an analysis focused environment? The answer will depend very […]
Session 11: Units in FEA – some horror stories!
Units can cause a lot of errors in FE Analysis… Video : 60 minutes presentation and curated Q and A Conversion between unit systems is one of the biggest problems The errors can be due to simple ‘finger trouble’ Or They can be very difficult physical units US (old Imperial) to Metric is probably the most […]
