Notes:
1. All element stress output is in the local coordinate system. The
direction and sense of the element stresses are explained in
Fig. 1.13.
2. To obtain element stresses at a specified point within the
element, the user must provide the location (local X, local Y)
in the coordinate system for the element. The origin of the
local coordinate system coincides with the center of the
element.
3. The 2 nonzero Principal stresses at the surface (SMAX &
SMIN), the maximum 2D shear stress (TMAX), the 2D
orientation of the principal plane (ANGLE), the 3D Von Mises
stress (VONT & VONB), and the 3D Tresca stress (TRESCAT
& TRESCAB) are also printed for the top and bottom surfaces
of the elements. The top and the bottom surfaces are
determined on the basis of the direction of the local z-axis.
4. The third principal stress is assumed to be zero at the surfaces
for use in Von Mises and Tresca stress calculations. However,
the TMAX and ANGLE are based only on the 2D inplane
stresses (SMAX & SMIN) at the surface. The 3D maximum
shear stress at the surface is not calculated but would be equal
to the 3D Tresca stress divided by 2.0.
