6. SE and F modeling#
6.1. Characteristics of the models#
In these models, the C and D models are re-used, but the quantities obtained as a result of buckling due to the shock are evaluated using the behavior CHOC_ENDO_PENA of the operator DYNA_NON_LINE. Modeling E is without shock damping, while for modeling F damping is added.
We model the system with a material point and a discrete point whose material is DIS_CHOC_ENDO [U4.43.01].
6.2. Characteristics of the mesh#
Number of knots: 2
Number of mesh: 1 SEG2
6.3. Tested sizes and results#
The values of the quantities associated with the buckling of the wall are tested.
