SS-V: 1030 Simply Supported Thin Plate
Test No. VS04 Obtain the displacement at the center of a simple supported thin plate for concentrated load and uniform pressure load.
Definition
A square plate simply supported on four edges (Figure 1) is subjected to the following loads (Figure 2):
- uniform pressure
- concentrated load
The units are IPS.
Because solid model is used, boundary conditions on supported edges are applied along middle lines of these edges (Figure 3).

Figure 3.
The material properties are:
- Properties
- Value
- Modulus of Elasticity
- 1.7472e+7 psi
- Poisson's Ratio
- 0.3
Results
The following table summarizes the displacement at the center [in].
| Theory (Kirchoff's Plate Bending Model) | SimSolid | % Difference | |
|---|---|---|---|
| Uniform load | 4.0620E-06 | 4.0700E-06 | 0.20% |
| Point load | 1.1600E-05 | 1.1610E-05 | 0.09% |
