The von Mises stress can be enriched by a sign in order to know if we are dealing with traction or compression. This tutorial show you the workflow.

Stress Signed = *σ**vM*** sign*(**σ**PMax)*

List of features to use :

- Result variables
- Result Probe

A 150 mm beam and section 10x10 mm² where a flexion is applied.

Figure 1: von Mises stress on the left and Max Principal stress on the right

Create variables for Max Principal Stress and von Mises Stress with the feature “Result Variable”.

Figure 2: Variables creation

See below the list of variables:

The result probe creation where we define the formula using the 2 variables created just before.
