Abstract
The velocities of elastic relief waves in commercial aluminum (AD1) and aluminum alloy (D16) samples compressed by a shock wave were measured by the most direct method. Using these results together with the relationship for the three-dimensional velocity of sound as a function of the intensity of the sound wave (derived on the assumption that the shock adiabat and the one-dimensional release isentrope coincide when expressed in pressure/mass-velocity coordinates), Young's modulus, the shear modulus, and the Poisson coefficient are calculated for shock-compressed aluminum.
