Session 4: Why is Mohr’s circle so disliked? Giving it another chance … 30 minutes presentation, 30 minutes curated Q and A Mohr’s circle seems to be a very unpopular topic in structural mechanics courses! I think it is because it seems to be: Very arcane Very procedural Very confusing Never used in practical […]
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 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 7: Topology Optimization and Generative design – buzzwords or reality?
Generative Design is the new buzzword – but what is it? Video : 60 minutes presentation and curated Q and A Generative Design seems to have taken over from ‘Light-weighting’ or ‘Topology Optimization’ What do all these terms mean? Are they different technologies? This webinar takes a step back to look at what […]
Session 8: Why are Normal Modes an essential foundation in Dynamic Response?
A lot of Dynamic Response Analyses are carried out with no attempt to investigate Normal Modes Video : 60 minutes presentation and curated Q and A Dynamic Analyses may dive straight into: Transient Dynamic Analysis Frequency Response Analysis Shock Response Analysis Random response Analysis In my view – a Normal Modes survey is […]
Session 9: Stress Singularities and Concentrations
Are the stresses around local features real or imagined? Video : 60 minutes presentation and curated Q and A In some circumstances, the stress levels that we predict from FEA are not physically meaningful. The stress distribution and high levels of stress locally can be described as an FEA ‘artifact.’ The most common […]
