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 […]
A data driven world
Letting woes I have been letting a very small property in the UK for many years now. It is always a challenge when it is time to find a new tenant. This summer seems to have been particularly difficult, so whilst in the UK recently, I phoned the realtor to see what was happening. I […]
FEA Demos and Benchmarks
The last few months of this year have been busy. I have taught live classes to Rolls-Royce in Derby, UK, at the NAFEMS aerospace event in Wichita and most recently at Autodesk University in Las Vegas. I’ve also been teaching my regular e-Learning sessions. It’s nice to meet people face-to-face at the live events, and […]
