v2.02.016 SDLL16 - Free-free thin ring with a point mass

Summary:

The dynamic linear elasticity test is used to validate straight beam elements POU_D_T.

This test case concerns a free-free thin circular ring with a point mass.

The frequencies are tested by comparing simulation results with the reference solution AFNOR (ref. [1]) as well as those obtained with the Pipestress software.
