(absolute combination of axial, bending-y and bending-z)
stresses.
For PRISMATIC sections, if AY and/or AZ is not provided, the
full cross-sectional area (AX) will be used.
For TAPERED sections, the values of AY and AZ are those for the
location where the stress is printed. Hence at the location 0.0, the
AY and AZ are based on the dimensions of the member at the start
node.
The PRINT ELEMENT STRESSES command must be used to print
plate stresses (SX, SY, SXY, SQX, SQY), moments per unit width
(MX, MY, MXY) and principal stresses (SMAX, SMIN, TMAX)
for plate/shell elements. Typically, the stresses and moments per
unit width at the centroid will be printed. The Von Mises stresses
(VONT, VONB) as well as the angle (ANGLE) defining the
orientation of the principal planes are also printed.
The variables that appear in the output are the following. See
Figure 1.13 in Section 1 of this Reference Manual for more
information regarding these variables.
SQX = Shear stress on the local X face in the Z direction
SQY = Shear stress on the local Y face in the Z direction
MX = Moment per unit width about the local X face
MY = Moment per unit width about the local Y face
MXY = Torsional Moment per unit width in the local X-Y plane
SX = Axial stress in the local X direction
SY = Axial stress in the local Y direction
SXY = Shear stress in the local XY plane
VONT = Von Mises stress on the top surface of the element
VONB = Von Mises stress on the bottom surface of the element
TrescaT = Tresca stress on the top surface of the element
TrescaB = Tresca stress on the bottom surface of the element
SMAX = Maximum in-plane Principal stress
SMIN = Minimum in-plane Principal stress
TMAX = Maximum in-plane Shear stress
