Finding Stress and Displacement of elements in contact with an analytic rigid body
Finding Stress and Displacement of elements in contact with an analytic rigid body
(OP)
I have an analytic rigid surface indenting onto a deformable body. It all works and I have no errors, however I have to do a stress vs strain graph
I was wondering whether anyone could explain to me how to find the average stress/displacement of all the elements (and only these elements) which come into contact with the rigid punch.
Is there an easy way to do this? Do I have to select every individual element which touches the analytic surface? Thank you for any help

The reason I want an average is because I have a flat punch going onto a near infinite surface, and the average stress would allow me to look at the behaviour of the surface in general.
The elements by the edge of the punch have a much greater stress on them, however by averaging with the rest of the surface, we are able to gather a clearer picture of how the surface acts under a load.
I know it sounds like a stretch, but it makes sense in terms of the experiment.

i imagine abaqus has a method similar to FeMap for putting a selection of elements into a "group" or region or something.
i'm not so sure that the average stress is telling you much ...
