The dissertation presents a mathematical modeling approach for the high-speed flexible linkage mechanisms equipped with bonded piezoelectric sensing/actuating elements employing a mixed variational approach with Hamilton's principle in conjunction with the finite element formulation. This model includes both the terms coupling the elastic and rigid-body motions of linkage mechanisms and the terms coupling the elastodynamics and piezoelectricity of the elements, incorporating their effects upon the mass and stiffness matrices which are in general non-symmetric.
