Abstract
In work the problem about the shift established fluctuations piezoelectric semi-infinite space (piezoelectric a class 6mm hexagonal symmetry) on which boundary surface it is attached dielectric a layer of small thickness with part by part constant elastic factor is considered. Fluctuations of environment are raised with the help of a linear source vibration the dielectric layer enclosed on a surface. Using a method integrated Fourier, the problem is reduced to decision Fredholm of the integrated equation of the second sort, the admitting decision by a method consecutive approximation. It is shown, that on a contact site of a dielectric layer and piezoelectric semi-infinite space pressure on a line of the unit dielectric has logarithmic feature. Are received asymptotic formulas for an induction of an electric field, electric potentials and movings of far points of a site of contact.
