Integration points
(OP)
Hi experts,
Could someone tell me where are stresses and displacements calculated? Are they calculated at the nodes or at the integration points?
Thanks and regards,
Siddharth Premkumar.

RE: Integration points
In FE post-processing packages, the stresses can be listed/contoured at the integration points or can be extrapolated to the nodes. Most packages show stresses as contour plots, and by default these are either a pure extrapolation at the nodes, or an extrapolation PLUS averaging across elements.

Alternatively you might want to consult Robert D Cook's book on "Finite Element Modelling for Stress Analysis" page 60 under 'Plane Stress'. Very informative and practical explaination/discussion on this issue.
