COMPUTATION OF THE ENTROPY OF A TWO-PHASE ELASTIC MEDIUM IN THE PROBLEM OF THERMOELASTICITY

摘要

$1St. Petersburg State University 28, Universitetskii pr., Petrodvorets, St. Petersburg 198504, Russia; ;We find an explicit expression for the entropy of a homogeneous isotropic two-phase elastic medium in the problem describing the quasistationary process of changing the temperature. Based on the limit behavior of the entropy, we can conclude whether this process is reversible or not. Bibliography: 4 titles.
