Abstract

Thermally induced irreversible changes in mechanical properties of collagen-containing tissue such as tendon are analyzed in order to characterize the process of thermal denaturation of the collagenous matrix in tissues. Based on a simple phenomenological model of a partially denaturated tissue as a binary system consisting of an amorphous phase (denaturated collagen) and a structurized phase (collagen fibrillar structure), the consideration of the temperature-dependent evolution of the elastic module of a thermally modified tendon tissue is carried out. The activation energy of collagen denaturation is estimated with the use of experimental dependencies of the tendon elastic module on the temperature and heating time, which have been obtained by M.S. Wall et al.
