SS-V: 1130 Skew Plate Under Pressure

Definition

Figure 1.

A skew plate (Figure 1) is subjected to uniform pressure.

The load is 0.7 KPa. The plate is simply supported at the perimeter: Uz = 0 along edges AB, BC, CD, and AD. Ux = Uy = 0 at point A and Uy = 0 at point B to prevent rigid body motion.

Results

Two spot-points were created at the plate corners A and B in the mid-plane. This allows for application of constraints which eliminate rigid in-plane translation-rotations of the plate (Figure 2).

Figure 2.

To simulate simple supports, four spot-lines were created at the plate mid-plane around the plate perimeter (Figure 3).

Figure 3.

Vertical constraint Uz = 0 was applied to the spot-lines.

Final loading is shown in Figure 4.
