Abstract
The 2D electro-elastic fields in the piezoelectric layer-substrate structure with the general line defect are found. The considered line source consists of the four coinciding straight sources: the line of forces, the charged line, the dislocation line and its electrostatic analogue. Electrically, the surface of the layer is supposed to be either metallized or adjoined to an isotropic dielectric medium. Mechanically, two boundary problems are also considered: the surface is free, and the surface is clamped. The solutions obtained for a general case of unrestricted anisotropy are presented in a form of convergent Fourier integrals. The integrands are implicitly expressed in terms of the eigenvalues and the eigenvectors of the generalized Stroh matrix. Their finding needs additional computing.
