Sažetak
An attempt has been made to investigate analytically the mechanical behaviour of an open-circuited piezoquartz bar, one end of which is subjected to some prescribed electrical and thermal excitations while the other end is kept fixed. The method of operational calculus has been utilised and the numerical results are illustrated graphically. For time-scale ranging from 0 to 1 s variations of the displacement were found to be of the order of 10-6 to 10-8 m. Significantly, some disturbances persist at t=0 for linear and exponential input signal while the displacement ceases at t=0 in case of periodic input signal. The nature of the graph is found to be parabolic in case of exponential input whereas a linear relationship is obtained in case of periodic and linear input signals.
