Hello Everyone,
I am currently working on a linear static FEA with stress concentrations. I have not refined the mesh on the stress concentrations. The average stress in another region/surface without the stress concentration from 2mm-9mm mesh size has shown consistent output of about 30MPa, so i know the mesh setup has converged except on the stress concentration (represented by the max stress) which is showing a different behaviour. Trying to understand this behaviour.
My point of view is that, from 2mm - 5mm, the stress concentration is starting to be more pronounced and is growing exponentially in the results,
while from 5mm - 7mm, i believe this is a region where the stress concentration is not growing exponentially yet ( I can use results from this region),
while at 8mm and 9mm, (details below), I am not sure how to explain it.
Not included in this attaachment is: [mesh size(mm), max stress(Mpa)], [8,15713],[9,14552] which are way off.
Am I interpreting the results properly? What are your thoughts on the results?
