Numerical methods for low velocity impact with an experimental example.

What is it about?

We clarify a numerical method that is often cited but not properly described and compare it to a few other methods that have been developed throughout the years to solve the same impact problem. The predictive capabilities are assessed by an experiment with a wood beam.

Why is it important?

By being clear in our exposition of a numerical method and combining it with an experimental example, this problem can be a textbook case for understanding low-velocity impact and classical mechanical vibrations.
