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 […]
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 […]
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 […]
