“…Chitturi and Shaikh 39 studied the dynamic characteristic of fibreglass and thermoplastic polycarbonate hybrid plates subjected to transverse impact loading. Kareem and Majeed 40 analysed the transient behaviour of thick and thin symmetric, as well as the anti-symmetric cross-ply hybrid (glass–carbon/epoxy) laminated composite–shallow–shells using a novel HSDT kinematic model. Similarly, the transient dynamic responses of the polyester composite reinforced by different advanced fibres (E-glass and E-glass/carbon hybrid) subjected to low-velocity impact are investigated numerically using the HSDT kinematic model and corroborated with the experimental data.…”

The finite-element time-dependent deflection and stress responses of the shallow composite panels subjected to variable mechanical loadings (uniformly distributed load and sinusoidally distributed load) are reported in this article. The study reveals the influence of the advanced fibre hybridization (glass–carbon–kevlar) on the dynamic responses and establishes the accuracy of the numerical responses by comparing them with the experimental values. The numerical steady-state deflections of the hybrid composite structure are evaluated using a generic mathematical model derived through Reddy's third-order shear deformation in conjunction with the finite-element technique and Newmark's time integration scheme. The experimentally evaluated mechanical properties of the fabricated composites are utilized in the computations. The validity of the computed solutions is ascertained with in-house experimental (transient deflection) results. Besides, the numerical model is extended to assess the parametric dependence (aspect ratio, thickness ratio, curvature ratio, geometry, hybrid schemes and support conditions) of the dynamic deflection/stress responses of hybrid composite shallow shell panels subjected to variable mechanical loading types.

The time-dependent deflection values of the flat/curved hybrid fibre (Glass–Carbon–Kevlar)-reinforced composite panels under the influence of the mechanical loading (UDL and SDL) and the elevated thermal environment are analyzed in this research. To compute the numerical responses, a higher-order kinematic model is prepared considering the effect of single/double curvature of the shell panel. The weak form of the governing equation is established through the variational technique. The steady-state deflections are obtained by solving the discrete form of governing equation of transient vibrations using finite element method (FEM) by employing Newmark’s time integration method in MATLAB environment. The isoparametric Lagrangian element (nine-noded) is adopted to discretize the system equation of the hybrid panels. The validity of the numerical solutions, computed using the experimental hybrid composite properties, is verified with the experimental (in-house) results as well as with the benchmark results available in the published literature. Finally, the parametric study of dynamic deflection characteristics of hybrid composite shallow shell panels is carried out by varying the parameters such as curvature ratio, support conditions, hybrid schemes and type of loading in the elevated thermal environment and the results are discussed in detail.
