    Laminated composite structures are being used in many applications, including aerospace, automobiles, and civil engineering applications, due to their high stiffness to weight ratio. However, composite structures suffer from low ductility and sufficient flexibility to resist against dynamic, particularly impact loadings. Recently, a new generation of laminated composite structures has been /impact-analysis-of-mr-laminated-composite-structures.   effects of elastic tailoring, e.g., composite ply angles, on bend and twist deformations of composite beams. Chandra21 reported results of SMA bender elements embedded in composite beams for delivering bend and twist authority to composite rotorcraft blades. Baz and Ro22 also incorporated bender elements within sleeves on the neutral axis of

    In a fibrous composite laminate reinforced with piezoelectric filaments, for example, passing an electric field in the fibers generates stresses and strains which propagate through the composite medium due to constraints that exist both at the micromechanical, ply level, and the macromechanical, laminate :// Miki, M. and Sugiyama, Y.

    The dynamic response of laminated composite beams subjected to distributed moving masses is investigated using the finite element method (FEM) based on the both first-order shear deformation theory (FSDT) and the classical beam theory (CLT). Six and ten degrees of freedom beam elements are used to discretize the CLT and FSDT equations of motion, :// A family of sinus finite elements for the analysis of rectangular laminated beams.
