1. Reference problem#

1.1. Geometry#

The following system is considered:

1.2. Material properties#

The characteristics of the system are:

  • \({k}_{1}={k}_{2}=1N/m\)

  • \({m}_{1}={m}_{2}=1\mathit{kg}\)

  • \(e=1m\)

  • \(K=30N/m\)

1.3. Boundary conditions and loads#

The left edge of the system is fixed and the masses move along the axis of the springs.

1.4. Initial conditions#

We try to follow the evolution of the periodic solution from the second mode of the underlying linear system (contactless system).
