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

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.
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...
On a construction job, where I was working as a welder and
steel-erector, I visualised a special-purpose "crane" / lifting and
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.
