What does LOC mean in the General Stress Report?
Total stress is calculated every 15 deg and the zero degree axis for the total stress location angle in a clockwise direction around the pipe. The 0 degree axis is the local axis of the pipe cross-section, i.e. perpendicular to the pipe axis, corresponding to the resultant in-plane bending moment.
For example, if the local bending moments are my and mz, then arctan (my/mz) is the location off the 0 degree reference axis for the general stress location relative to the local y axis.
Note: For straight pipe in-plane bending is arbitrary since no plane of bending like an elbow.
Axial stress: fx/A
in-plane bending stress: my/Z
out-plane bending stress: mz/Z
fx = local axial force
my = local in-plane bending moment
mz = local out-plane bending moment
