“…The nonlinear vibration of thin-walled rotating laminated composite circular cylindrical shell with arbitrary boundary conditions based on Donnell’s nonlinear shell theory and using the incremental harmonic balance method have been illustrated by Li et al (2020). Ye et al (2020) have been studied the free vibration and transient dynamic analysis of composite cylindrical shell with magneto-electro-elastic face sheet using scaled boundary finite element method (FEM). Also, the effects of the structural parameters, material properties and boundary conditions on the vibration and dynamic behaviors of cylindrical composite shell have been studied.…”

Free vibration analysis of adhesive joins between two laminates circular cylindrical along with conical laminated composite shells considering various boundary conditions are examined. The numerical analysis are studied based on the first order shear deformation shell theory (FSDT) and considering compatibility conditions. Using Hamilton principle method, the governing equations of composite cylindrical shell lap adhesive joined to the composite conical shells are obtained. The analysis for carbon/epoxy, glass/epoxy and aramid/epoxy laminated composite materials and various type of adhesive materials are studied. For solving the equilibrium equations of lap joined the cylindrical to the conical shells with adhesive layer, the generalized differential quadrature method (GDQM) is used. The effect of circumferential wave number, length to radius ratio of the shell, length of overlap to length of shell ratio, thickness to radius ratio and thickness of adhesive to thickness of shell ratio are investigated. Furthermore, the various cone angles of conical shell, type of materials and adhesive layer on the natural frequency of laminated circular cylindrical connected to the conical shells are studied. In order to validate the numerical results of present analysis with previous research compared that the result shown that these comparisons show very good agreement. Numerical results shown that with increasing the value of cone angle of the conical shell and the ratio of overlap length to shell length, due to increasing the structural stiffness, the non-dimensional frequency of the structure with adhesive layer increased.

“…24 In addition to this, the natural frequency also varied with the geometrical parameters of the structures. 25 Chen et al 26 expounded on the vibrational behavior of multilayered MEE plates under different boundary conditions. The numerical results show that the addition of lateral clamped boundary conditions increases the eigen frequencies by 50-100% when compared to the free-boundary condition.…”

This article deals with the modeling of magneto-electro-elastic auxetic structures and developing a methodology in COMSOL Multiphysics® to assess the free vibration response of such structures when subjected to various electromagnetic circuit conditions. The triple energy interaction between elastic, magnetic, and electric fields are established in the COMSOL Multiphysics® using structural mechanics and electromagnetic modules. The multiphase magneto-electro-elastic material with different percentages of piezoelectric and piezomagnetic phases are used as the material. In the solid mechanics module, the piezoelectric and piezomagnetic materials were created in stress-charge and stress-magnetization forms, respectively. The electric and magnetic fields are defined in COMSOL Multiphysics® through electromagnetic equations. Further, the customized controlled meshing constituted of free tetrahedral and triangular elements is adapted to trade-off between the accuracy and the computational expenses. The eigenvalue analysis is performed to obtain the natural frequencies of the MEE re-entrant auxetic structures. Also, the efficiency of smart auxetic structures over conventional honeycomb structures is presented throughout the manuscript. In addition, the discrepancy in the natural frequencies of the structures considering coupled and uncoupled state is also illustrated. It is believed that the modeling procedure and its outcomes serve as benchmark solutions for further design and analysis of smart auxetic magneto-electro-elastic structures.

“…Therefore, the ability of the desired coupling effect in multi-physical fields has been pain attention to by numerous scholars. It is not surprising that the mechanical and physical behaviors in the MEE composites like wave propagation [22,23], dislocation [24,25], contact [26,27], crack [28,29], buckling and postbuckling [30], bending and vibration control problems [31][32][33] have been widely investigated for providing a theoretical basis to design and manufacture the intelligent composites.…”

In the paper, a novel magneto electro elastic ( model of bi-directional ( 2 D) functionally graded material s (FGM s ) beam s is developed for investigating the nonlinear dynamics It is shown that the asymmetric modes induced by the 2D FGM s may significantly affect the nonlinear dynamic responses which is tremendously different from previous studies Taking into account the geometric nonlinearity, the nonlinear equation of motion and associated boundary conditions for the beam s are derived according to the Hamilton’s principle The linear frequencies and modes of the beam s are numerically calculated by the generalized differential quadrature method (GDQM) GDQM). The frequency responses of the nonlinear forced vibration are constructed based on the Galerkin technique incorporating with the incremental harmonic balance (I HB) approach. The influences of the material distributions, length thickness ratio, electric voltage, magnetic potential as well as boundary condition on the nonlinear resonant frequency and response amplitude are discussed in details. It is notable that increasing in the axial and thickness FG indexes, negative electric potential and positive magnetic potential can lead to decline the nonlinear resonance frequency and amplitude peak which is usually applied to accurately design the multiferroic composite structures.
