Calculating the impact force of a mass on an elastic
... The mass free-falls over a distance d and contacts the structure. It then falls by an additional amount, u, after contact with the structure. The deformation of the structure, through the distance u is determined by the elastic deformation of the structure it falls upon. I presume that, once the el ...
