The paper concerns description of the thermoelastic phenomenon in an auxetic rectangular plate within the extended thermodynamical model. Analyzing vibrations of that plate a dependence of elastic constants on the frequency, particularly of Poissons ratio of auxetic state of the body has been presented. Moreover, considered investigations allow to determine the thermal relaxation time analyzing resonance frequencies of the vibrating plate.
