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 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 12: Can Designers really take advantage of FEA?
Video : 60 minutes presentation and curated Q and A Given a design, the big question is, who will carry out the FE analysis If it is the designer: Is it more efficient to do this within a CAD embedded environment, or divert the task to an analysis focused environment? The answer will depend very […]
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 […]
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 […]
