Output of Plate Element Stresses and Moments
For the sign convention of output stress and moments, please see
Fig. 1.13.
ELEMENT stress and moment output is available at the following
locations:
A. Center point of the element.
B. All corner nodes of the element.
C. At any user specified point within the element.
Following are the items included in the ELEMENT STRESS
output.
SQX, SQY Shear stresses (Force/ unit len./ thk.)
SX, SY, SXY Membrane stresses (Force/unit len./ thk)
MX, MY, MXY Moments per unit width (Force x Length/length)
(For Mx, the unit width is a unit distance
parallel to the local Y axis. For My, the unit
width is a unit distance parallel to the local X
axis. Mx and My cause bending, while Mxy
causes the element to twist out-of-plane.)
SMAX, SMIN Principal stresses in the plane of the element
(Force/unit area). The 3
rd
principal stress is 0.0
TMAX Maximum 2D shear stress in the plane of the
element (Force/unit area)
ANGLE Orientation of the 2D principal plane (Degrees)
