Abstract
Dynamic behavior of a piezoelastic symmetrical cross-ply rectangular laminate subjected to mechanical and electrical loads and simply-supported is investigated considering the effect of damping due to interlaminar shear. The behavior of the laminate is analyzed based on the first-order shear deformation theory. To incorporate the effect of damping due to interlaminar shear, the interlaminar shear stresses which satisfy the Newton's law of viscosity are introduced. Equations of motion in terms of deflection and rotations are derived and solved by the Laplace transform method. The transient deflection due to dynamical loads are obtained. The methods to control the deflection due to mechanical load by applying electrical voltage to the piezoelectric actuators are investigated by showing numerical calculations.
