The influence of the characteristics of the external circuit on the form of the electric pulse in the tasks of direct piezoeffect

The axisymmetric non-stationary problem of electroelasticity for a solid piezoceramic axially polarised cylinder is considered under the kinematic load in the form of well-known mechanical displacements of its face surfaces, as well as the electric potential. The new closed solution is constructed by vector eigenfunction decomposition method in the form of structural algorithm of finite transformations. The obtained calculation relationships allow analyzing the influence of the external circuit characteristics on the form and sizes of the induced electric pulse in nonstationary problems of direct piezoeffect.
