nonlinear static analysis of smart Laminated Composite Plate
Aerospace Science and Technology, 2011Co-Authors: M Hari D V Kishore, B N Singh, Mihir K. PanditAbstract:Abstract In this paper, a third order shear deformation theory is used to study the behavior of Laminated smart Composite Plate with magnetostrictive layers, while accounting for geometric nonlinearity in the von-Karman sense. A coupled analysis of magnetostrictive material is presented where Terfenol-D is used as a magnetostrictive material to control the responses of the Laminated smart Composite Plates. A C 0 finite element formulation is proposed for this purpose. The accuracy of the present formulation has been shown by comparison of the present results with those available in the literature. Some new results are also presented for future research in this field of study.

post buckling response of Laminated Composite Plate on elastic foundation with random system properties
Communications in Nonlinear Science and Numerical Simulation, 2009Co-Authors: B N Singh, Rakesh KumarAbstract:Abstract This paper deals with second order statistics of post buckling load of shear deformable Laminated Composite Plates resting on linear elastic foundation with random system properties. The formulation is based on higher order shear deformation Plate theory in general von Karman sense, which includes foundation effect using two-parameter Pasternak model. The random system equations are derived using the principal of virtual work. A finite element method is used for spatial descretization of the laminate with a reasonable accuracy. A perturbation technique has been the first time successfully combined with direct iterative technique by neglecting the changes in nonlinear stiffness matrix due to random variation of transverse displacements during iteration. The numerical results for the second order statistics of post buckling loads are obtained. A detailed study is carried out to highlight the characteristics of the random response and its sensitivity to different foundation parameters, the Plate thickness ratio, the Plate aspect ratio, the support condition, the stacking sequence and the lamination angle on the post buckling response of the laminate. The results have been compared with existing results and an independent Monte Carlo simulation.

Three dimensional static and free vibration analysis of cross-ply Laminated Plate bonded with piezoelectric layers using differential quadrature method
Meccanica, 2016Co-Authors: M. Feri, A Alibeigloo, A. A. Pasha ZanoosiAbstract:This paper illustrates static and free vibration analysis of a cross-ply Laminated Composite Plate embedded in piezoelectric layers based on three dimensional theory of elasticity. In this approach, a semi-analytical solution is presented for the hybrid Plate with arbitrary boundary condition. For analysis a differential quadrature method (DQM) is used in two directions and state space method is employed along the thickness direction. The method is validated by comparing numerical results with the one obtained in the literature and also the results of DQM are compared with the results of analytical solution obtained by Fourier series solution. In parametric study, the effect of boundary condition, mechanical load, electric voltage, length to thickness ratio and piezoelectric thickness on both vibration and static behavior of Plate are investigated.

effect of viscoelastic interface on three dimensional static and vibration behavior of Laminated Composite Plate
Composites Part B-engineering, 2015Co-Authors: A AlibeiglooAbstract:Abstract In this study, static and free vibration analysis of Laminated cross-ply rectangular Plate with special emphasis on incorporating viscoelastic interface is investigated using three-dimensional theory of elasticity. The Laminated Plate is assumed to be simply-supported at four edges and is subjected to uniform pressure at the top surface. State space technique is used along the Plate thickness to investigate the space dependent behavior where as time dependent behavior can be discussed by solving first order differential equation of sliding displacement at the viscoelastic interfaces. Numerical results depicts that the present method converges rapidly and good agreement is exist between the present results and the published results. Moreover, the effects of elastic and viscous interfaces, time, aspect ratio and length to thickness ratio on the bending and vibration behavior of Laminated Plate are studied.

Electro-Magneto-Elastic Response of Laminated Composite Plate: A Finite Element Approach
International Journal of Applied and Computational Mathematics, 2017Co-Authors: Goutam Dutta, Trupti Ranjan Mahapatra, Subrata Kumar Panda, Vijay K. SinghAbstract:The flexural behaviour of the Laminated Composite Plate embedded with two different smart materials (piezoelectric and magnetostrictive) and subsequent deflection suppression have been investigated in this article. The mathematical model of the Laminated Composite Plate embedded with and without smart materials are developed using the higher-order shear deformation kinematics in conjunction with finite element steps. The Plate is assumed to be subjected to the combined effect of the mechanical load, electrical potential and the magnetic field induction. The desired responses are computed numerically with the help of a homemade computer code developed in MATLAB environment in association with the present finite element formulation. The convergence and the validity of the presently computed numerical responses have been established by comparing the responses with those available numerical and analytical results. Further, the desired responses of the Laminated Composite structure bonded with and without functional materials are computed using the commercial finite element package (ANSYS) and compared with the present numerical results. Finally, the present higher-order model is extended to examine the static responses of the Laminated Composite Plate embedded with piezo and magnetostrictive material by solving the wide variety of numerical examples for different design parameters. The degree of deflection suppression capability due to the smart layers has been underlined and discussed in details.

nonlinear transient analysis of smart Laminated Composite Plate integrated with pvdf sensor and afc actuator
Composite Structures, 2016Co-Authors: Vijay K. Singh, Trupti Ranjan Mahapatra, Subrata Kumar PandaAbstract:Abstract In this article, the geometrically nonlinear transient response of the smart Laminated Composite Plate is investigated under the coupled electromechanical load. The Plate has been modeled using the higher-order kinematic model in conjunction with Green-Lagrange nonlinear strains. The electric potential across the sensor/actuator layer is modeled as the quadratic function of the thickness coordinate. The domain is discretized with the help of a nine noded isoparametric quadrilateral element with thirteen degrees of freedom per node. The desired transient responses are obtained using the direct iterative method in association with Newmark’s time integration scheme. In order to achieve distributed actuator and the sensor behaviour the active fibre Composite and Polyvinylidene fluoride fibre reinforced Composite are utilized along the poled fibre direction and through the thickness, respectively in this present investigation. In this analysis, two types of configurations of the sensor and actuator (collocated and non-collocated) are considered to compute the active stiffening responses. The convergence and the validity of the present numerical model have been checked. Finally, the effects of various geometrical parameters along with the sensor and the actuator arrangements on the nonlinear transient responses of the Laminated Composite Plate are examined by solving various numerical examples.

AIAA Journal, 2016Co-Authors: Sushree S Sahoo, Subrata Kumar PandaAbstract:The free vibration, bending, and transient responses of Laminated Composite Plates have been investigated with delamination in this present study. The Laminated, Composite, shear deformable Plate has been modeled mathematically using two higher-order shear deformation theories in conjunction with finite element steps. The final form of the governing equations of the bending and the free vibration responses are obtained using the variational method and the classical Hamilton’s principle, respectively. In addition, the transient responses are computed using Newmark’s time integration scheme for the discrete coupled second-order ordinary differential equation system of the dynamic equilibrium. The desired free vibration, bending, and transient responses are computed numerically using a homemade computer code developed in the MATLAB environment and compared with those available published numerical and analytical results. Finally, the importance of the developed higher-order models has been studied by analyzin...
