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 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 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 […]
Session 2: FEA quick sanity checks
Session 2: FEA quick sanity checks 30 minutes presentation, 30 minutes curated Q and A Making sure we don’t fall into the trap: “Garbage in – Garbage out” is vital in FEA. I show some sanity checks we can use in static and dynamic analysis to quickly make sure we are on the right […]
