Abstract

A new class of bimorph actuators, called C-block actuators for their curved shape, have recently been proposed to provide improved performance characteristics over conventional straight bimorph actuators. Existing mathematical models of these actuators are based on classical curved beam theory which neglects transverse shear effects. The paper presents an improved mathematical model for C-block actuators of arbitrary thickness. The new model accounts for through-the-thickness transverse shear deformations using refined displacement fields. The results from this theory are compared to the existing classical model and experimental data. Both free and forced end conditions are investigated. An exact elasticity solution is also developed which provides a framework for comparison of the developed theory and other approximate theories.
