Temperature dependence of amplitude-dependent dislocation damping
Abstract
A theory of the damping due to the break-away of dislocations from pinning points given by the authors for low temperatures has been extended into the high-temperature range by taking into account thermal activation during break-away. It has been found that in the high-temperature range the amplitude dependence is described by the same formula as in the low-temperature range (Granato-Lücke formula) but the parameters have a different meaning.
