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.
