Abstract
Second- and third-order elastic-constant data have been used to determine the Grüneisen mode , average-square Grüneisen constant , and nonlinear constant for Cu, Ag, and Au. The attenuation suffered by longitudinal ultrasonic waves propagating in the and directions and transverse waves polarized along and , owing to the phonon viscosity and thermoelastic phenomena, have been evaluated for the three metals at 293 °K. The phonon viscosity and dislocation drag along the and directions are also discussed.
