1. Reference problem

1.1. Geometry

Direction of travel: \(\theta =45°\) in the \(\mathrm{XY}\) plane

1.2. Material properties

Spring stiffness:	\(k=10000N/m\)
Point mass:	\(m=1\mathrm{kg}\)
Gravity:	\(g=10m/{s}^{2}\)
Coulomb coefficient:	\(\mu =\mathrm{0,1}\)

1.3. Boundary conditions and loads

The system is based on plane \(Z=0\) on which it can slide with a Coulomb coefficient of friction of \(\mu =\mathrm{0,1}\).

1.4. Initial conditions

Initial displacement of the mass: \({r}_{0}=\mathrm{0,85}\mathrm{mm}\) in the \(\theta\) direction.

Zero initial speed.
