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 […]
Session 5: Nonlinear buckling cheats
Session 5: Why is cheating needed in nonlinear buckling analysis Video 1: 40 minutes presentation Video 2, 25 minutes curated Q and A The first time I did a nonlinear buckling analysis; I set up a cylinder model, applied the load – and waited. What a letdown! The cylinder just compressed, went […]
Session 10: ‘Spider’ Elements in FEA, what are they?
Spider elements play a big role in traditional FE Analysis Video : 60 minutes presentation and curated Q and A Every FE Analyst develops a toolbox of favorite techniques The Rigid and Flexible ‘spider’ elements are an essential part of mine Spider element is an ‘unofficial’ term I use because … The elements allow a ‘spider’ […]
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 […]
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 1: St Venant’s Principle
Session 1: St Venant’s Principle 30 minutes presentation, 30 minutes curated Q and A This principle is often quoted in FEA. It is a very generalized statement, but what does it mean and how can we use it in practice? I explore the background to the principle and discuss how it can be used […]
