In this paper, the free vibration of a bi-directional functionally graded (2D-FG) nanobeams is investigated by the finite element method. Nanobeams are made of two kinds of porous materials. The material properties of 2D-FG nanobeams are assumed to vary in both axial and thickness directions according to a power law . Based on Eringen's nonlocal elasticity theory, the governing equations of motion are derived.

The paper "Continuous Element formulations for free vibration of FGM annular plates resting on elastic foundation" introduces an efficient approach for analyzing the vibration of functionally graded annular plates resting on elastic foundation. The Continuous Element for annular plates on Winkler-Pasternak foundation is constructed based on the analytical closed form solution of the differential equations of the investigated structure.

This work focuses on the free vibration of the functionally graded porous (FGP) sandwich microplates using the isogeometric approach (IGA). The FGP sandwich plate comprises the homogeneous core and the FG porous face sheets. The material properties of the FGP face sheets are supposed to vary through the thickness direction according to the power-law function and modified rule of a mixture of the volume fraction with three different types of porosity distribution: homogeneous porous, X porous and V porous distributions.

This article investigates the free vibration of the porous metal foam plates resting on an elastic foundation based on the isogeometric approach (IGA). The elastic foundation is modeled as a two-parameter of Winkler and Pasternak foundations. The pores are assumed to vary through the thickness direction in three types: uniform, symmetric and asymmetric distributions.

In this study, the nonlocal elasticity theory is applied to analyze the free vibration of the functionally graded nanobeams. The novelty of the present study is that the classical nonlocal elasticity theory has been modified to take into account the variation of the nonlocal parameters through the thickness of the functionally graded. nanobeams.

This research presents Dynamic Stiffness formulations for studying dynamic behavior of composite inner/outer ring-stiffened cylindrical shells. The continuous elements investigated in this paper are cylindrical and ring elements. Base on dynamic stiffness matrix of the above elements, an assembling procedure is proposed to solve the problem of complex composite inner/outer ring-stiffened cylindrical shells.

The derived temperature dependences of the peak intensities, separations and half-widths of the separate spectral peaks in the A-band phonon progressions indicate the different trends for vibration-free zero-phonon electronic transition and vibration-related lower-energy electronic transitions to high vibrational levels of the ground electronic state – lower thermal damping and more softened phonon for the zero-phonon transition, also implying the extended defect origin of the A-band photoluminescence.

In this work, the free vibration analysis of Timoshenko microbeams made of the Functionally Graded Material (FGM) on the Winkler–Paternak elastic foundation based on the Modified Coupled Stress Theory (MCST) is investigated. Material characteristics of the beam vary throughout the thickness according to the power distribution and are estimated though Mori–Tanaka, Hashin–Shtrikman and Voigt homogenization techniques.

A damage diagnosis method for trusses based on incomplete free vibration properties utilizing ensemble learning, e.g. Extreme gradient boosting (XGBoost), is presented in this work. Owing to the lack of measurement sensors, modal features are only measured at master degrees of freedom (DOFs) of a few first models instead of all DOFs of a structural system.
