2018-11-5  A typical dent is on the order of a millimeter, and a typical hammer speed at impact is probably ~ 10 meters/sec. The duration of the impact would be approximately equal to 1/10,000 sec. The force would be on the order of: f = 2 k g ∗ 20 m / s e c / ((1 m m) / (10 m / s e c)) = 400,000 Newtons.

Most of the dynamic pile-driving formulas are based on the fundamental energy equa­ tion wherein the kinetic energy of the hammer's ram at impact is equated to the work done on the pile, that is, the product of the distance the pile moves and the soil force resisting this movement. However, several complicating factors must be accounted
