My Finite Element Analysis pages

Getting started 2016

The initial study and learning of FEA modelling

My initial 46-day programme

My initial 46-day programme - applying a Finite Element Analysis modelling computer-package to engineering challenges which I have previously encountered in my career - without concerning myself about how Finite Element Analysis works "under the hood" (North-American English) / "under the bonnet" (British English) (in likeness to driving a car without knowing how a car works)

Then my 22-day study of the mathematical basis of FEA

My subsequent surprise step - taking an interest in and studying the mathematical basis of Finite Element Analysis .

FEA Structural Study of a T-junction between H-column sections

I encountered a poorly-performing structure where a horizontal beam was intersected at its mid-length by a side-column. Quite small side-forces applied to the top of the column produced large displacements (it was not very rigid), and permanent deformation readily resulted, giving a permanently inclined column.

My instinct was that stiffener-plates spanning the web of the intersected beam would be very beneficial.
Here is my FEA model of the structure without and with stiffener-plates .

FEA of folded thin-plate steel machine chassis

Finite Element Analysis modelling using shell-elements for an economic FEA solution contributing to a new high-performing category of machine-chassis becoming economically feasible for ad-hoc applications.

FEA convergence vs local geometry investigated

Time for me to investigate this topic - and it proved to be very informative "giving it a whirl". The abstruse (?) case of fillet-weld weld-toe geometry proved a winner...

FEA of a visualised wheeled lifting equipment

On a construction job, where I was working as a welder and steel-erector, I visualised a special-purpose "crane" / lifting and transporting device.
Lifting equipment of all forms in the UK comes under the legislative reach of the "Lifting Operations and Lifting Equipment Regulations 1998" ("LOLER").
In this case, the potential advantages makes worthwhile the effort of proving a custom equipment.
Finite Element'ing this conceptualised mobile lifting-frame is part of that safety-case. As well as overall showing the idea.

FEA 2021

FEA of "beam-configuration fillet-weld tensile test"

I made this real-world physical test for the strength of fillet welds; the beam-configuration fillet-weld tensile test - the BCFWTT.
I used FEA to analyse how it behaved. Essentially; does it do what I'd like it to be doing (answer : yes)

FEA of hydraulic piston

Compares response to pressure of plain disc piston ("simple") and piston with stiffer plates ("stiffened"). The FEA analysis of pistons .

Fillet welds 2016 and 2017 as a single page

No new content. The new webpage re-presents previous work for a different purpose. I've combined and edited (mainly trimmed) the 2016 and 2017 investigations into performing Finite Element Analysis modelling of fillet welds, becoming an article on what Finite Element Analysis modelling shows about fillet welds.
