SSV: 1130 Skew Plate Under Pressure
Test No. VS14 Find the maximum principle stress at the skew plate center at point E.
Definition
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.
The material properties are:

 Value
 Modulus of Elasticity

Results
Two spotpoints were created at the plate corners A and B in the midplane. This allows for
application of constraints which eliminate rigid inplane translationrotations of the plate
(Figure 2).Figure 2.


To simulate simple supports, four spotlines were created at the plate midplane around the
plate perimeter (Figure 3).Vertical constraint Uz = 0 was applied to the spotlines.
Final loading is shown in Figure 4.
Maximum principle stress distribution at the plate bottom is shown in Figure 5.
*The reference solution is from analytical solution for thin plate formation.
