The transport case for this heavy, high-value drill bit must be able to sustain a drop of six feet without damage to the drill bit, damage to the threads on the drill bit pin, and without the latches securing the top to the case separating. An explicit dynamics finite element analysis in which all the surfaces may contact was used.
The case must not tear and the forces in the latches must not exceed their capacity.
The properties and thickness of the foam were sized such that the foam does not fully compress during or after the impact.
