## 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
.

## Orthotropic Bridge Deck

orthotropic bridge deck
- a lighterweight bridgedeck stiffened by longitudinal U-ribs and
transverse T-bars

# FEA 2107

## 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...
