Question:
Is it also possible to display principal stresses as trajectories or vectors?
Answer:
The vectorial display of principal stresses is possible if displaying the angle alpha under the stresses in the Results navigator.
The values for Sigma‑1 and Sigma‑2 are then displayed separately for the stress in the direction of the principal axes on the positive/negative surface side, and the membrane stress in the direction of the principal axes in the vector form.
You can control the trajectory scale by the factor for trajectories in the control panel.
