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).
