v3.06.100 SSLA100 - Infinite cylinder subjected to a field of volume and surface forces

Summary:

This linear quasistatic mechanics test makes it possible to validate the assignment of a force field load, surface or volume.

The structure studied is cylindrical. The fields at the volume density and force area nodes are read from a file in Ideas format. For volume loading, the field read varies quadratically as a function of the distance from the axis; for surface loading, the field read corresponds to an internal pressure.

Three models of the same problem are carried out:

• 3D modeling;

• axisymmetric 2D modeling;

• 2D modeling plane deformations;

The reference solution is analytical.
