v5.01.105 SDND105 — Impact of a material point against a wall with plastic buckling

Summary:

This test validates the behavior of a shock-type obstacle with possible buckling. The resolution was carried out with the operator DYNA_VIBRA using the keyword FLAMBAGE (models A, B, C and D) and with the operator DYNA_NON_LINE using the behavior CHOC_ENDO_PENA (models E and F).

The moment of onset of buckling (this moment corresponds to the first moment when the shock force has exceeded the buckling threshold), the cumulative plastic deformation and the moment when one returns to the initial position are calculated.

The results obtained are in agreement with the analytical results.
