OS-V: 0040 Z-Section Cantilever

Test No. LE5 OptiStruct examines the axial (x-x) stress (compression) at mid-surface, point A for linear static analysis.

Figure 1. FE Model with Boundary Conditions and Loadcases

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 0.6MN each are applied.

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

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
