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 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 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 […]
Who’s on First; Hooke or Young?
A Good Question I was teaching the “Introduction to Finite Element Analysis” training course in Holland recently. A design engineer on the course came up with a good question relating to a graph I had just sketched up on the whiteboard. I was describing how a material will respond to the loading, in terms […]
