Abstract
In this paper, we consider the solution of the problem of the theory of piezoelectricity. The effective elastic, piezoelectric, and dielectric characteristics are calculated for a two-layer composite with a volume concentration of layers of 50%. The corresponding characteristics are calculated for a two-layer material with an orthogonal-reinforced structure. For the numerical solution of the problem, the conjugate gradient method for solving systems of algebraic equations was used. The results were visualized using a software package developed at Bauman Moscow state technical University. The paper presents the distribution of the stress field σij and the vector in problems Lr and Lpq .
