Abstract

This article presents closed form natural frequency solutions for two classes of mechanically coupled laminate with: extension-bending or; extension-twisting and shearingbending. Details on the derivation of these two laminate classes are given; all of which contain combinations of standard ply angles, e.g. +45, -45, 0 and 90°. Upper and lower bounds on the non-dimensional natural frequencies are shown graphically for each class of laminate over a range of aspect ratios. Finally, differences are highlighted between these bounds and others obtained by the simplifying assumption that the two laminate classes contain only cross plies or angle plies, respectively.
