TL;DR: In this paper, a dynamic finite element method for free vibration analysis of generally laminated composite beams is introduced on the basis of first-order shear deformation theory, where the influences of Poisson effect, couplings among extensional, bending and torsional deformations, shear deformations and rotary inertia are incorporated in the formulation.

TL;DR: In this paper, the exact dynamic stiffness matrix of a uniform laminated composite beam based on trigonometric shear deformation theory is derived, and a refined laminated beam constitutive equation is derived that takes into account the breadth direction strains.

TL;DR: In this article, the dynamic transfer matrix is formulated for a straight uniform and axially loaded thin-walled Bernoulli-Euler beam element whose elastic and inertia axes are not coincident by solving the governing differential equations of motion of the beam element.

TL;DR: In this paper, a dynamic stiffness method is introduced to investigate the free vibration of laminated composite beams based on a third-order shear deformation theory which accounts for parabolic distribution of the transverse shear strain through the thickness of the beam.

TL;DR: In this article, a dynamic transfer matrix method for determining natural frequencies and mode shapes of the bending-torsion coupled vibration of axially loaded thin-walled beams with monosymmetrical cross sections is developed by using a general solution of the governing differential equations of motion based on Bernoulli-Euler beam theory.
