Abstract : A Boltzmann equation approach is used to investigate the phonon distribution in a solid undergoing finite amplitude shock loading. Phonon-phonon interactions, via the anharmonic content of the crystal, lead to a collision term in the spirit of the Callaway thermal conductivity model. The theory is used to consider the phonon-phonon attenuation of a shock wave. In order to complement the microscopic theory, some macroscopic theory is considered. (Author)
