Thermoelastic waves in a continuum with complex structure

A mechanical two‐component model of the solid of complex structure is presented. The suggested structural‐rheological model is governed by a system of equations describing dynamics of thermoelastic body of complex structure and accounting for the force and energy exchange between the material components of the body. Propagation of mechanical and temperature disturbances due to a pulse laser excitation is considered. The influence of the material structure on the character of transfer of the temperature disturbances is studied. The possibility of transfer of temperature disturbances with the velocity close to that of the mechanical pulse propagation is shown.
