Coupled wave processes in piezoceramic bodies at the electric discharge

Acoustic bulletin, Vol. 2 1, (1999) p.60-73
Boundary problems on the nonstationary deformation of piezoceramic bodies at the electric discharge have been formulated on base of generalization of the theory of condensor's discharge by Rompe-Weizel. The detailed analysis of wave field in the cylindrical sparkle generator has been held out. The trends have been investigated that depict the changes in the pulse current and difference of electric potentials under the discharge process and afterwards. There has been presented the comparison of the results obtained on base of generalization of the theory of condensor's discharge and the earlier results obtained using the theory of instant discharge.
