v5.01.101 SDND101 - Release of a spring mass system with shock

Summary

This problem corresponds to a transient analysis by modal recombination of a discrete non-linear system with one degree of freedom. Nonlinearity consists of contact with shock on a rigid plane. The mass is launched with a non-zero initial speed against the obstacle. The initial game between the material point and the obstacle is zero. This problem makes it possible to test the post-treatment of impact forces: shock speed, shock duration…
