Abstract :
We study the effect of heat conduction on the shift in the frequencies of a freely vibrating linear piezoelectric body by using two perturbation methods. It is shown that the first order effect on frequencies is to shift them by a small imaginary number signifying thereby that the effect of energy dissipation due to heat conduction is to reduce the amplitude of vibration
