C modeling
==============


Characteristics of modeling
-----------------------------------

The cantilever beam is 0.35 m long and extends between X = 0.15 m and X = 0.5 m. It is modelled in 3D close to the embedment (between 0 and 0.22 m) and continues with a beam modeling. The surface connection is made to the node located in the 0.22 m situation by the 3D_ POU option of the LIAISON_ELEM keyword of AFFE_CHAR_MECA.

The structure is modelled by Timoshenko beam elements (POU_D_T) and linear hexahedral elements (HEXA8).

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).
