Drop Shock Formula

[Talos]

Anybody know the formula for calculating a free fall drop shock from a known height(ie deceleration assuming a half sine)

I would check MIL-STD-810F method 516.5 "Shock"

Also, if this application is commerical testing of equipment packaging? Here is a link to FedEX packaging. We had some of our special packaging tested by FedEX

The basic answer is that there is no canonical value, since your half-sine has a duration, which is what actually drives the max amplitude, and that's a function of the object your drop and the surface on which you drop it.
