Topic: Equivalent stresses

Hi,

is it possible to display Tresca and/or von Mises stress? In GiD I didnt find out how to display them in postprocessing. But I think there has to be an option because the equivalent stresses are in most cases more important than the principal ones.

Best regards,
Devka

Re: Equivalent stresses

Hello, in a fully nonlinear analysis, the inelastic deformations (crack openings, plastic strains, etc.) are typically much more of interest than any stresses (especially after cracking/plastizations start to develop). If you wish a scalar value measuring plastic deformations, look at "Equivalent plastic strain".

For the "Bilinear Steel von Mises" material model, a new data attribute "Mises Equivalent Stress" is available in the current development version now being tested (5.0). If you wish to try the pre-release, please send an email to our general support address, including your ATENA User ID (WR). Mention that you wish to try the "Mises Equivalent Stress".
