Abstract
We present a new 2-noded beam element based on the refined zigzag theory and the classical Euler-Bernoulli beam theory for the static analysis of composite laminate and sandwich beams. The proposed element is able to take into account distortion effects clue to shear elastic strains and can predict delamination. The element has four degrees of freedom per node. A C-1 cubic Hermite interpolation is used for the vertical deflection while a C-0 linear interpolation is employed for the other kinemat...
