Reply To: Stress concentration calculation at joints (Hotspot Stress)

You should use the SeamWeld solver in Ansys nCode DesignLife for this type of analysis.  In lieu of using DesignLife, you can use stress linearization in Mechanical to obtain a “hot spot” stress.  You could linearize along the length of the weldment (as shown in the image), but it is probably more accurate to linearize through the weldment thickness.

Why do you want to edit principal stress output?  What output do you want?
