Abstract
Boundary-value problems of piezoelastic equilibrium in a 3-D formulation are considered. The direct approach boundary integral equation and the set of equations of piezoelasticity are written in the same form as the equation set of anisotropic elasticity. To obtain components of the matrices of fundamental and singular solutions, their integral and polynomial representations are used. For the transversally isotropic case, explicit forms of these components are used. Examples of the boundary-element analysis of boundary-value problems are given.
