5.3 Academic Example

5.3.1 Simply-supported Plate under Uniform Loading

A square plate with the dimensions of 22 m and
thickness of 0.01 m is shown in the figure. The plate is made from
2
a material that has the Young’s modulus of 7.2 10 10 N/m and
Poisson’s ratio of 0.25. The plate is simply supported along its
2
four edges and is subjected to a uniform pressure of 1,200 N/m .
We will employ ANSYS through the Workbench to solve for the
plate deflection and stresses.

Steps for analyzing this plate bending problem by
employing the ANSYS Workbench are as follows.

(a) Starting ANSYS Workbench

 Open the ANSYS Workbench, set the Units menu on the

upper tab to Metric (kg,m,s, C,A,N,V).
 On the Analysis Systems window, click twice on the Static
Structural item. A new small box will appear on the
Project Schematic window.
 Retype the name in the lower blue tab as the desired project
name, e.g., Simply-supported Plate, and hit Enter.
