4. B modeling

4.1. Characteristics of modeling

Discretization of the two beams by a SEG2 mesh and 2D_ DIS_T type finite elements.

The resolution is done in time using the DYNA_VIBRA command on a modal basis with the TRBDF2 schema.

4.2. Characteristics of the mesh

Number of knots: 2

Number of meshes and types: 1 SEG2

4.3. Tested sizes and results

The infinite norm of the difference between the analytical solution and the solution calculated at the level of mass no. 3 is evaluated. This comparison is made for displacement, speed, and acceleration.

Identification	Reference value	Reference type
Infinite norm difference displacement mass 3	0	“ANALYTIQUE”
Infinite norm difference speed mass 3	0	“ANALYTIQUE”
Infinite norm difference acceleration mass 3	0	“ANALYTIQUE”
