Micromechanics model for coated-fiber piezoelectric composites

摘要

A piezocomposite with coated cylindrical fibers of a circular cross section are considered. The fibers are parallel to each other and randomly located in the transverse plane. The composite cylinder assemblage model is adopted and simple formulae are derived for all the effective constants, except for the transverse shear modulus. This last parameter is estimated by a mean field theory approximation.
