Abstract: The effective properties of piezoelectric composite materials are very important in engineering. In this paper, the closed-form solutions of the constraint-strain and the constraint-electric-field of a transversely isotropic spherical inclusion in an infinite non-piezoelectric matrix are obtained. The dilute solutions of piezoelectric composite materials with transversely isotropic spherical inclusions are also given. The solutions in the paper can be readily utilized in analysis and design of piezoelectric composite materials or smart materials and smart structures.

Key words: piezoelectric composite materials, inclusions, constraint-tensors, the effective electro-elastic moduli
