We will now review the von Mises stress results, a stress tensor result, and plate/shell display options available in the Results environment.

von Mises. The stress results appear as shown in the following image.

Settings
Plate/Shell Options. Notice that, by default, the
Total Stress/Strain is displayed, and the
Two-Sided Display
option is set to
Both. Alternatively, you can view only the portion of the total stress or strain that is due to bending. Similarly, you can view only the membrane stress/strain (that is the stress/strain associated with pure in-plane tension or compression.
When bending is present, stress and strain at the top of a plate/shell element has a different value than at the bottom. Even though the actual elements only have one surface, the color or the contour plot is rendered differently when the top and bottom sides are facing you (assuming the default Both Sides option is active. For this reason, the maximum stress or strain might not be visible from a particular model viewpoint. You can reverse the sides or force the colors to be based on the top or bottom side regardless of the viewpoint.
For now, leave the Plate Display Options dialog open.

XX Component. This contour plot clearly demonstrates the reversal in the sign of the stress tensor between the top and bottom faces of the plate elements (due to bending). The model should resemble the left image in the table below.

A positive tensor result indicates tensile stress, and a negative tensor result indicates compressive stress. The plotted colors and legend values match the actual stress or strain only when the sides are not reversed.
