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 6: High Cycle or Low Cycle fatigue – what’s in a number?
What’s the real story behind the transition from Low Cycle to High Cycle fatigue? Video : 60 minutes presentation and Q and A The terms High Cycle and Low cycle fatigue are used extensively – but what is the real difference? Is the transition an arbitrary number; 1000 cycles, 100,000 cycles. As […]
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 […]
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 […]
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 […]
