Abstract
Background internal friction at the grain boundaries of general type
Incoming article date: 05.09.2021The results of the development of asymptotic expressions for the calculation of the background of internal friction at the boundaries of the General type for the limiting cases of frequency dependence are presented. Mathematical expressions are obtained on the basis of consideration of models of the border containing periodically located steps of alternating signs and the intercrystalline border of the general type consisting of parallel plane segments of the set width separated by alternating steps of identical height and cylindrical pores.
