The third order elastic constants of aluminum

The complete set of six third order elastic constants of single crystal A1 has been experimentally determined by measuring both hydrostatic pressure and uniaxial stress derivatives of the natural sound velocities using a two specimen interferometric technique. The values obtained are ...in units of 101 2 dyn.cm -2 • I The specimens were neutron irradiated to eliminate dislocation effects~ from the uniaxial experiments. A se1fconsistent set ofhyd,rostatic pressure derivatives of the second order elastic constants has been calculated from the measured third order elastic constants. The' third order elastic constants have also been used to calculate the thermal expansion in the anisotropic continuum moqe1 at both high and low temperatures, and a comparison has been made to the directly measured expansion coefficients.
