Fig. 1From: Explicit Verlet time-integration for a Nitsche-based approximation of elastodynamic contact problemsMultiple impacts of an elastic bar. The bar is clamped at \(x=L\) and the contact node is located at the bottom. The closed-form solution is periodic of period 3, with one impact during each period (here between \(t=1\) and \(t=2\))Back to article page
