Summary
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.
Details
Stress Signed = σvM* sign*(σPMax)
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:
