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
