Abstract:

Annealed copper balls of the type used in tarage and crusher gages were compressed at compression speeds from 0.01 inmin to about 400 ftsec. It was found that the force-deformation curve at any two velocities of compression are related as the ratio of the mean velocities of compression. The force-deformation curve roughly follows that of a spring-mass system however, a more accurate method is described which gives pressures from large explosions which are much closer to actual piezoelectric gage measurements than found by previous calculations.
