Benchmark Model
Quad4 and Quad8 elements are used to create a uniform mesh of 8 elements along the length with one element across width of flange. All the displacements at one end are maintained zero, at the other end two uniformly distributed force of 0.6M N each are applied.
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 (-108 MPa Compression).
Quadrilateral Shells | Axial Stress (x-x) at Mid-surface Point A (MPa) | Normalized with the Target Value |
---|---|---|
Quad4 | -112.2 | 0.962566845 |
Quad8 | -110.9 | 0.973850316 |
