Format – live presentation around 30 minutes. Q and A 30 minutes . Completed presentation recordings to view Session 1. St Venant’s Principle […]
Session 3: Free Body Diagrams
Session 3: Free Body Diagrams – what are they and why do they go wrong? 30 minutes presentation, 30 minutes curated Q and A Free body diagrams are used in structural analysis to try to reduce the problem to its simplest description. Where does the load get applied and where does the load get […]
Session 4: Mohr’s circle
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 10: ‘Spider’ Elements in FEA, what are they?
Spider elements play a big role in traditional FE Analysis Video : 60 minutes presentation and curated Q and A Every FE Analyst develops a toolbox of favorite techniques The Rigid and Flexible ‘spider’ elements are an essential part of mine Spider element is an ‘unofficial’ term I use because … The elements allow a ‘spider’ […]
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 […]
