“…The results showed that the linear and nonlinear frequencies relating to the symmetric distribution of carbon nanotubes in thickness direction were more than those of uniform and asymmetric distribution of nanotubes. Mohebpour et al [33] examined the dynamic analysis of composite beams using the finite element and Newmark method with the Consideration of the shear and rotary inertia effects. Yas and Samadi [34] numerically studied the free vibrations and buckling analysis of carbon-nanotube-reinforced composite Timoshenko beams on elastic foundation.…”

A temperature-dependent vibration analysis is conducted for the functionally graded nanocomposite beams which are reinforced by graphene. Material properties are assumed to change along the beams in five different types based upon the graphene distribution with a specific function. The differential equations of motion are extracted and solved using the spectral numerical method for the beams under various boundary conditions. The effect of distribution of functionally graded nanocomposite in the thickness direction of beams on the frequency response of vibration, and the effect of various parameters on the vibration response has been examined, such as the distribution function of nanographene plates, weight percentage, dimensions of nanographene plates, temperature changes, and thickness ratio. The results are compared and validated with numerical and analytical results reported in references for manifold boundary conditions. It is seen that the increase of graphene weight percentage in all boundary conditions will cause an increase in the natural frequency of the beams.

“…In Kadivar et al [19], the one dimensional finite elements based on classical lamination theory, first-order shear deformation theory, and higher-order shear deformation theory are developed to study the dynamic response of an unsymmetric composite laminated orthotropic beam. Mohebpour et al [20] presented the free vibration and moving oscillator problems of isotropic and composite laminated beams using the finite element method. In other researches, they studied the dynamic behavior of the composite beam using analytical approximations.…”

This paper presents a numerical study of the free and damped forced vibration of simply-supported beams with composite coats subjected to a moving load by use of finite elements method. Three types of beam configurations, aluminum, composite and strengthened beam are investigated. The equation of motion of the beam is solved using the modal superposition method and integrated by applying the Newmark time integration procedure. Good agreements were achieved between the FEM and analytical solutions. The damped dynamic response, critical velocities and the dynamic amplification factor of the beam are calculated for different parameters such as the thickness ratio, the fiber orientation of the coat and damping ratio.

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, respectively. The resulting spatially discretized beam governing equations including the effect of inertial, Coriolis, and centrifugal forces due to moving distributed mass are evaluated in time domain by applying Newmark’s scheme. The presented approach is first validated by studying its convergence behavior and comparing the results with those of existing solutions in the literature. Then, the effect of incline angle, mass, and velocity of moving body, layer orientation, load length, and inertial, Coriolis, and centrifugal forces due to the moving distributed mass and friction force between the beam and the moving distributed mass on the dynamic behavior of inclined laminated composite beams are investigated.
