A couple of days ago I wrote a new webpage on using Finite Element Analysis modelling to predict the effect of different weld toe shapes on the Stress Concentration Factor (SCF) there."FEA simulation of fillet-weld "toe" with specific weld features"
All the resources - images, renderings, graphs, etc. and the key points of my text - are from 2016 and 2017 and re-used in a different way as "this is about welds and here is what FEA can do for welds".
I am able to do that because this first application of FEA for my own purposes having worked through the tutorials has stood the test of time.
There you have it - for what it's worth... Hope is of interest to some of you.
Best message is "Finite Element Analysis modelling is very approachable and usable now"
