Micromechanical modeling and effective properties of the smart grid-reinforced composites

smart composite structures reinforced with a periodic grid of generally orthotropic cylindrical reinforcements that also exhibit piezoelectric behavior are analyzed using the asymptotic homogenization method. the analytical expressions for the effective elastic and piezoelectric coefficients are derived. in particular, the smart orthotropic composite structures with cubic, conical and diagonal actuator and reinforcement orientations are investigated.
