The present investigation deals with the thermoelastic interaction in an unbounded fiber-reinforced anisotropic medium with a cylindrical cavity. The three-phase-lag (3PL) thermoelastic model and Green and Naghdi model (GNIII) are employed to study the thermophysical quantities. In the threephase-lag model, the equation of heat conduction a containing fourth order derivative with respect to time. The cavity surface is subjected to ... إقراء المزيد
