Nonlinear Damped Vibrations of a Laminated Composite Plate Subjected to Blast Load

Nonlinear Damped Vibrations of a Hybrid Laminated Composite Plate Subjected to Blast Load

“…The hybrid plate is composed of two basalt fabric plies, two Kevlar/epoxy plies and two E-glass/epoxy plies, respectively. Kazancı and Mecitoğlu [21] have derived the equations of motion of the damped vibrations of a laminated plate subjected to blast load. They have obtained the nonlinear dynamic equations of a laminated composite plate in terms of mid-plane displacements, using the constitutive equations and the strain-displacement relations in the virtual work and applying the variational principles, as follows:…”

The Nonlinear Dynamic Behaviour of Tapered Laminated Plates Subjected to Blast Loading

“…The explicit expressions of the operators L ij and N i are given in an Appendix and also can be found in Kazancı and Mecitoglu [2]. The boundary conditions for a simply supported plate can be given in the following form: …”

“…Using the constitutive equations and the strain-displacement relations in the virtual work and applying the variational principles, nonlinear dynamic equations of a tapered laminated plate can be obtained in terms of mid-plane displacements as [1,2]:…”

“…In a paper on the effect of the blast load, the nonlinear damped vibration of a simply supported laminated composite plate is studied theoretically [1]. In the other two studies, in-plane stiffness and inertias are considered in the analytical solution of the laminated composite plate under the blast load [2,3]. In a study on the effect of blast loading, the dynamic response of sandwich panels is investigated [4].…”

“…In-plane stiffness and inertia effects are also taken into account in the formulation of the problem. The equations of motion for the plate are derived by the use of the virtual work principle [1,2]. The displacement-time and strain-time histories are obtained on certain points through the tapered direction.…”
