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 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 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.

TL;DR: In this paper, the use of active non-linear absorber to control the high-amplitude vibration of the nonlinear plant subjected to primary external excitation is investigated, which exploits the saturation phenomenon that is known to occur in dynamical systems with quadratic nonlinearities and a two-to-one internal resonance.

TL;DR: In this article, high-amplitude response suppression of the primary resonance of a nonlinear plant under cubic velocity feedback control is investigated by means of the multiple scales method, two equations on the amplitude and phase of the response of the nonlinear system are obtained and the force-response and frequency-response curves are shown.
