The pressure dependence of the damping constant for a moving dislocation hasbeen calculated and evaluated with the intension of being compared with our resultsof high pressure experiments. The calculations were made on the basis of themechanisms of phonon scattering (Leibfried, Klemens, and Brailsford), ther-moelastic effect (Eshelby), phonon viscosity (Mason), and fluttering effect (Ninomiya).Pressure derivatives of various quantities appearing in the formulations of thesemechanisms were firstly calculated, and then the pressure dependence of the dampingconstant was evaluated. The higher order elasticity theory could conveniently be usedin these calculations. The numerical evaluations were made for the cases of LiFNail, and Al crystals. The experimental second- and third-order elastic constantsand the theoretical fourth-order elastic constants were adopted in these evaluations.
