2. Benchmark solution

2.1. Calculation method used for the reference solution

In linear elasticity, cf. [V6.02.117] a comparison is made to other numerical results obtained with Code_Aster on a \(\mathrm{3D}\) mesh of the elbow and straight parts, connected at the ends to straight beams. This \(\mathrm{3D}\) mesh includes 1024 HEXA20 meshes. A COQUE_3D model gives similar results.

2.2. Benchmark results

For a moment applied \(\mathrm{Mz}\) in \(D\), moving \(\mathrm{DY}\) from the same point \(D\) is equivalent to:

2.3. Uncertainty about the solution

Since the reference solution is numerical, the precision can be evaluated from [§2.2] to \(\text{2\%}\) by comparing solutions \(\mathrm{3D}\) and COQUE_3D.
