Abstract. The problem of the mechanical disturbances of an open-circuit piezo-quartz bar, the one end of which is subjected to some prescribed electrical and thermal excitations while the other is kept fixed, has been investigated in the present study. The problem involves interaction of three fields, viz., mechanical, electrical and thermal. The method of operational calculus has been utilized and the numerical results are illustrated graphically. For time-scale ranging from 0 to 1 s variations of mechanical disturbances are found to be of the order of 10-4 m.
