Summary
This paper presents the results of a simplified theoretical analysis to estimate both the effects of friction and inertia durting fast compression of a cylinder. The solution enables to eliminate stress errors developed in experiment due to presence of friction and inertia. Using this analysis it was attempted to estimate the static and dynamic coefficient of friction by compression of aluminum specimens of ten height-to-diameter ratios in the range from 0.1 to 1.0. It is concluded that the dynamic coefficient of friction, as estimated from experiments with the split Hopkinson bar /lubrication by the MoS2 powder/, is a bit larger than that estimated from the quasi-static experiments.
