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:

Young's Modulus
210 x 103 MPa
Poisson's Ratio

Linear Static Analysis Results

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