my question is about the Equivalent Von-Mises stress output. I would like to get a clarification about its interpretation to check for validation of the model. I know it is the square root of the stress along the principal axes, thus it is always positive.
If I have a model subjucted to a force vector is it right to assume that the red coloured areas of the Equivalent stress plot, which are of higher magnitude) refer to a compression? Or it includes also the tension? This because looking at the reaction forces the output doesn't behave as the force applied requires.
Any response will be appreciated.
