TLDR
In this article, the impact compressibility of different aluminum alloys in the test pressure range is weakly dependent on chemical composition, treatment process, and material strength, and the boundary for a marked effect of strain rate on its resistance moves into the region of higher rates.Abstract:
1.
Within the limits of experimental error, the impact compressibility of different aluminum alloys in the test pressure range is weakly dependent on chemical composition, treatment process, and material strength.
2.
Resistance to deformation in the high strain rate region increases with increasing strain rate, and the boundary for a marked effect of strain rate on its resistance moves into the region of higher rates.
3.
In the case of the absence of a correlation between strength properties with uniaxial stress and uniaxial strain states, their sensitivity to loading rate may be connected with a single viscosity factor.read more

TL;DR: In this paper, the authors used a modified version of a torsional Hopkinsonbar to investigate the plastic flow of materials at high rates and found that the initial response of the material is essentially rate dependent.
