“…In a study on the effect of blast loading, the dynamic response of sandwich panels is investigated [4]. The nonlinear structural response of laminated composites subjected to blast loading is also investigated experimentally and theoretically [5,6]. The theoretical results are found to be in an agreement with the experimental ones qualitatively.…”

Abstract. In this study, the geometrically nonlinear dynamic behaviour of simply supported tapered laminated composite plates subjected to the air blast loading is investigated numerically. In-plane stiffness, inertia and the geometric nonlinearity effects are considered in the formulation of the problem. The equations of motion for the tapered laminated plate are derived by the use of the virtual work principle. Approximate solution functions are assumed for the space domain and substituted into the equations of motion. Then, the Galerkin method is used to obtain the nonlinear algebraic differential equations in the time domain. The resulting equations are solved by using the finite difference approximation over the time. The effects of the taper ratio, the stacking sequence and the fiber orientation angle on the dynamic response are investigated. The displacement-time and strain-time histories are obtained on certain points in the tapered direction. The results obtained by using the present method are compared with the ones obtained by using a commercial finite element software ANSYS. The results are found to be in an agreement. The method presented here is able to determine the nonlinear dynamic response of simply supported tapered laminated plates to the air blast loading accurately.

“…For a thin plate subjected to a blast load, Birman and Bert [11] indicated that the contribution of the higher-order modes is smaller compared to the first-order mode shape for plate aspect ratio less than 3. Turkmen and Mecitoglu [12] also noted that the mode shape of a plate is not affected by the number of terms in the series used in the linear analysis range. In the case of a thin glass plate, because of glass strength limitation, the deformations cannot be too large and hence not comparable to those of a metal or composites plate subjected to blast loading.…”

“…Bauer [9] and Teng et al [10] studied dynamic large deflection response of an isotropic elastic plate subjected to blast loading using the von Karman nonlinear plate equation and employed the perturbation method to solve the nonlinear equations. Based on the von Karman large deflection theory, Birman and Bert [11] and Turkmen and Mecitoglu [12] studied laminated composite plates under blast loading. The equation of motion obtained by using the Galerkin method was solved by Runge-Kutta method.…”

“…Mitchell and Reddy [1] proposed the theory of laminated plates with piezoelectric by using both classical and simple third-order plate theories. Turkmen and Mecitoglu [2] conducted both theoretical and experimental studies of the composite laminated plates exposed to normal blast shock waves and presented a correlation with numerical and experimental results of the strain time histories. Under harmonic transverse excitation, Oh and Nayfeh [3] used the experimental method to study nonlinear combination resonances in cantilever composite laminated plates.…”

An asymptotic perturbation method is presented based on the Fourier expansion and temporal rescaling to investigate the nonlinear oscillations and chaotic dynamics of a simply supported angle-ply composite laminated rectangular thin plate with parametric and external excitations. According to the Reddy's third-order plate theory, the governing equations of motion for the angle-ply composite laminated rectangular thin plate are derived by using the Hamilton's principle. Then, the Galerkin procedure is applied to the partial differential governing equation to obtain a two-degrees-of-freedom nonlinear system including the quadratic and cubic nonlinear terms. Such equations are utilized to deal with the resonant case of 1:1 internal resonance and primary parametric resonance-1/2 subharmonic resonance. Furthermore, the stability analysis is given for the steady-state solutions of the averaged equation. Based on the averaged equation obtained by the asymptotic perturbation method, the phase portrait and power spectrum are used to analyze the multi-pulse chaotic motions of the angle-ply composite laminated rectangular thin plate. Under certain conditions the various chaotic motions of the angle-ply composite laminated rectangular thin plate are found.angle-ply composite laminated plate, third-order shear deformation theory, parametric excitation, chaotic motion Citation:GUO X Y, Zhang W, Yao M H.
