4. B modeling#

4.1. Characteristics of modeling#

The 0.35 m long cantilever beam, extending between X = 0.15 m and X = 0.5 m, is entirely modelled by Timoshenko beam elements (POU_D_T).

DYNA_VIBRA (transient calculation on a physical basis) calculates the dynamic response of the structure, due to a nodal force of 500 N applied at the end node of the 1D mesh (located at X = 0.5 m).
