05.11.2018 The force between hammer and anvil is indeed very difficult to calculate. There are two significantly different cases 1 where the interaction is elastic no permanent deformation of either the hammer or the anvil and 2 where the interaction is inelastic e.g. the hammer leaves a dent in the anvil . In both cases the force is related to the momentum change
