The investigation method consisting in approaching of complex presentation of compound electroelastic fields with next solution of homogeneous boundary problems of functions theory in corner regions. At consideration mixed electroelasticity dinamic problem mathematical procedures which are founded on reduction of boundary problems to systems of singular integral equations are developed. In results of investigation equations for determinations of stress singularities orders in the top of composite and homogeneous piezoceramic wedges, composite anisoropic wedges are obtained. The Green's function for composite piezoceramic wedge under different homogeneous boundary conditions are built. Calculations results of dinamic stress concentration on hole contour in piezoceramic medium, wave fields in piezoceramic cyl inder which is excitated by system of surface electroods are given. Procedures determination mechanical and electrical fields magnitudes near of tunnel inhomogeneity in piezoelectric cylinder are developed. More of results which are consisting in this work are new. They can be used in faille materials mechanics, in projection practice of SII and CB and etc. Product Description popup.authors popup.nrat_date 2020-04-03 Close
