Abstract

Models of the “chain in a thermostat” type, i.e., models on which the statistical physics of macromolecules is based, have been analyzed. It has been noted that these models ignore vibrational thermal motion. A model of the same type, referred to as the elastic-segmental and where the existence of this motion is taken into account, has been proposed. This motion is reduced to bending vibrations localized within a segment. Formulas for the free vibrational energy and deformation caused by local vibrations have been obtained. The proposed model is used to study the influence of local vibrations on the behavior of defects that can arise in cartilaginous tissue. A possible mechanism by which defects disappear under the influence of local vibrations has been considered.
