Abstract
The electro-elastic fields induced by the transversely 1D distribution of intrinsic strains in an arbitrary infinite piezoelectric plate with metallized surfaces are determined. The results obtained generalize the well-known theory of internal stresses in anisotropic purely elastic plates developed by Indenbom, Sil’vestrova, and Sirotin [1]. The coupled fields found in the piezoelectric are expressed in terms of the 4D formalism and the corresponding generalized planar tensor of electro-elastic moduli. It is shown that the limiting transitions from a piezoelectric plate to an unbounded medium and half-space lead to identical formulas.
