Problem

What is the SACS convention for plate stresses (Sx, Sy, Txy) in detail stress report?

Solution

Plate stress directions are represented in form of plate local axis coordinates. SACS considers Tension as positive and compression as negative. The stresses are reported at the plate neutral axis. Bending stresses are given at the upper surface of the plate (positive local Z direction) in the plate local co ordinate system. Plate stiffener stresses at the top (S+Z) and bottom (S-Z) are reported.

In case of unity check report, the stresses considered are maximum principal stress and maximum shear stress.
