Modeling Piezocomposite Actuators Embedded in Slender Structures

This work presents a comprehensive methodology for dimensional reduction of anisotropic slender structures with embedded anisotropic piezocomposite materials. The analysis is based on a variational-asymptotic formulation, and provides cross-sectional stiffness, inertia and actuation forces for a beam modeling of the structure. It can retain higher-order information corresponding to non-classical deformation modes. The particular case of the active anisotropic Timoshenko-like beam formulation is considered separately. Some results for typical active beam configurations are included and compared with three-dimensional shell finite element solutions using thermal analogy for the distributed actuation.
