# OS-V: 0060 Thick Plate Pressure

Test No. LE10 The model is a thick plate subjected to uniform normal pressure of 1MPa on the upper surface of the plate. OptiStruct examines the direct stress ${\sigma }_{yy}$ at the point D for linear static analysis.

## Benchmark Model

Second order Hexahedral, Penta and Tetra elements are used to create the coarse and fine mesh. A uniform pressure of 1 MPa is applied on the upper surface of the plate.

The material properties are:
Material Properties
Value
Young's Modulus
210 x 103 MPa
Poisson's Ratio
0.3

## Linear Static Analysis Results

All results are normalized with the target value (5.38 MPa).
