“…In their work, a viscoelastic core is embedded into a simply-supported composite beam and the nonlinear damping properties are explored by using the higher order zig-zag theories. Youzera et al [13] extended the previous work of [12] and investigated the normal transverse strain effect on the results. The passive control of composite beam can also be achieved by embedding shape memory alloy (SMA) specimens (usually SMA wires) in the composite materials.…”

“…As it is seen in [1][2][3][4][5][6][7][8][9][10][11][12][13][14], even in case of simple composite beam without SMA reinforcements, there is no accessible results for the nonlinear dynamic analysis of composite beam under arbitrary transient loads by using LWT beam model. Accordingly, in the current work, a nonlinear forced vibration analysis of SMA hybrid composite beams by using FOBT and LWT methods is sought.…”

A comprehensive study is provided to compare the results of layer-wise theory (LWT) with one of the renowned equivalent single layer beam theories (ESLs) known as First-Order shear deformation beam theory (FOBT) on the study of transient nonlinear dynamic response of an SMA reinforced composite beam. Considering von Karman strain-displacement formulations, the governing equations of forced vibrations under transient impulsive loads are formulated by LWT and ESL methods. In order to simulate the constitutive behavior of SMA wires, the 3D SMA model developed by Panico and Brinson is adopted and reduced to a 1D model which enables one to reproduce pseudo-elastic (PE), martensite transformation/orientation and in particular ferro-elastic (FE) effects. General transient transverse loading is considered and the governing equations are discretized by combined method of differential-integral quadratures (DQ-IQ). Based on Newmark time marching technique, an incremental solution algorithm is developed for the problem in which nonlinear governing equations are solved by Newton-Raphson method. The results are assessed by comparing with available literature. Moreover, the FOBT and layerwise solutions are compared with each other and the effects of layup geometry and boundary conditions upon the composite beam responds are explored. The influence of volume fraction of SMA-wire reinforcements and the FE/PE behaviors of the wires upon the diverging results of FOBT/LWT analyses are studied in detail.

“…The in‐plane behaviour of the masonry wall and cantilever structures (Figure 4a) in the free vibration problem is described by the HSDT theory, often considered for composite thick beams. [ 36–38 ] This theory is more realistic because they verify zero transverse shear stress condition at the top and bottom of the composite masonry wall. The HSDT was extensively used in linear vibration and buckling analyses of deep beams.…”

Summary In the present paper, a constitutive viscoelastic model for periodic masonry structures is proposed. Using a dynamic homogenization approach of the continuous and discrete‐based model leads to the determination of the anisotropic material properties by assigning the fictitious stress and strains of the homogeneous cell masonry unit. These properties are defined as complex moduli, which consist of real parts representing elastic stiffness and imaginary ones referring to energy dissipations. The advantage of the proposed model is that the damping properties associated to different modes of vibrations can be easily evaluated. Numerical and parametric investigations are conducted that reveal the capabilities of the model to an accurate prediction of the dynamic properties of the masonry walls mainly under both in‐plane and out‐of‐plane vibrations.

“…Numerical analyses are carried out to study vibration behaviour of composite laminated beams using ANSYS 15 software. Youzera and Meftah [24] carried out nonlinear forced vibration analysis of sandwich beam with viscoelastic core layer. In the analytical formulation, normal, transverse and shear deformations are considered in the core layer by mean of the refined higher-order zig-zag theory.…”

A high specific stiffness, high specific strength, and tailoring the properties for specific application have attracted the attention of the researchers to work in the field of laminated composites and Sandwich structures. Rapid use of these laminated composites and Sandwich structures necessitated the development of new theories that suitable for the bending, buckling and vibration analysis. Many articles were published on free vibration of beams, plates, shells laminated composites and sandwich structures. In this article, a review on free vibration analysis of shear deformable isotropic beams, plates, shells, laminated composites and sandwich structures based on various theories and the exact solution is presented. In addition to this, the literature on finite element modeling of beams, plates, shells laminated composites and sandwich structures based on classical and refined theories is also reviewed. The present article is an attempt to review the available literature, made in the past few decades on free flexural vibration response of Fiber Metal laminated Composites and Sandwich panels using different analytical models, numerical techniques, and experimental methods.
