“…where [𝜔] is the eigenvalue and {𝜙} is the eigenvector. Lanczos' method reduces the generalized problem to the standard form of a tridiagonal coefficient matrix, as shown in Equations (10)(11)(12)(13)(14). For extracting natural frequencies in interesting ranges, the frequency shift 𝜃 𝐿 is introduced to the generalized eigenvalue problem.…”

“…As a result, there is a great deal of interest in researching and comprehending the dynamic behaviour of composite structures. The study of modal parameters based on modal loss factors (damping), modal shapes, and resonance frequencies has played an important role in dynamic structural characterization, dynamic design, damage detection, and condition monitoring [6][7][8][9][10][11][12].…”

This paper investigates the free vibration analysis of kevlar/glass/epoxy resin hybrid composite laminates. The ABAQUS software is studied to obtain the natural frequency with different fiber hybridization effects. The 3D shell element models evaluate natural frequency and mode shape in the quasi-isotropic laminated composite. The numerical analysis results are studied and compared between ABAQUS and ANSYS software. It was shown that the natural frequency value between ABAQUS and ANSYS software provided almost the same value. The error value between ABAQUS and ANSYS ranged from 1.03 % to 2.30 %. It was found that the error between the experimental and numerical results was from 1.15 % to 13.51 %. It was concluded that the percentage error value was significantly dependent on the mesh size. Furthermore, the reasonable agreement between experimental and ANSYS results can better analyze the free vibration of composite laminates.

“…In addition, the effects of geometric parameters, material properties and boundary conditions of the structures on the free vibration response were investigated. It was concluded from the literature that frequency values increased with growing aspect ratio and orientation angles and the natural frequency is higher with the increase in the thickness of the beams (Prasad and Sahu, 2018;Harras et al, 2002;Merzuki et al, 2019).…”

PurposeThis study aims to demonstrate the numerical application of differential quadrature (DQ) methods and show the experimental application of free vibration analysis of fiber-metal laminated composite (FML) plates with various boundary conditions.Design/methodology/approachThe FMLs are hybrid structures consisting of fiber-reinforced polymer matrix composites such as carbon, glass, aramid and different metal sheets, and are currently widely used in the automobile, aircraft and aerospace industries. Thus, free vibration analysis of these hybrid materials is necessary for the design process. The governing equations of motion are derived based on the classical plate theory. The DQ, generalized DQ (GDQ) and harmonic DQ (HDQ) differential quadrature methods have been used to solve the governing equations of an FML composite plate numerically. The accuracy and convergence of the numerical model have been verified by comparing the results available in the published literature with the results obtained from these methods. Moreover, an experimental procedure has been performed in order to compare the results against those of the numerical methods.FindingsIt is noteworthy that a high degree of similarity and accuracy was observed between the numerical results obtained by the DQ methods and the experimental results. Thus, the present study validates the applicability of the DQ methods for designing the FML composite plates.Originality/valueIn this study, the advantages of the DQ methods have been demonstrated differently from previous studies on the vibration analysis of the FML plates.

“…Fibre metal laminates (FML) [5][6][7][8][9] consists of alternating layers of fibre reinforced polymer composites and metal alloys [10,11]. FMLs have improved resistance to impacts and environmental conditions due to the outer aluminium alloy layers [12][13][14][15]. Until now, FML is most popular and it is presently used for manufacturing of most part of aerospace structural component such as the aircraft engine cowlings, cargo floor and containers and seamless tube.…”

Fibre-metal laminates (FMLs) offer advanced improvements over current available structural materials due to the excellent mechanical properties. In this work, the dynamic behaviour of the carbon fibre/epoxy, glass fibre/epoxy, aluminium 2024-T0, and fibre metal laminates were carried out. Furthermore, the different type of reinforced composites in FMLs and the effect of the layer sequence of metal layers were investigated. The composite laminates have been manufactured by a hot press machine. The free vibration tests were conducted to determine the dynamic characteristics of the samples. The accuracy of the experimental results was verified by comparing the numerical analysis results. The results indicate that the effect of thickness and the layer sequences of metal layers have a significant effect on the natural frequency of the FMLs.
