v5.02.032 SDNL32 - Impact of an articulated beam on elastic support

Summary:

This problem corresponds to a transitory analysis by modal superposition of a non-linear system consisting of a flexible beam swung at one of its ends. It is animated by a rotational movement of a solid body at the initial moment and encounters an elastic stop with unilateral contact. The problem has a reference solution proposed by the Commission VPCS.

There is a modeling with POU_D_T elements. The vibratory dynamics operator is tested. Deviations from the reference solution do not exceed \(\text{0.8\%}\).
