“…In this paper, the contact depth was calculated in terms of energy. Kareem and Majeed 9 studied the dynamic analysis of a spherical shell subjected to low-velocity impact, experimentally, and numerically. In this paper, the equations of motion were obtained by using higher-order shear deformation theory (HSDT) and Hamilton's principle.…”

A new theoretical solution based on Layerwise theory is presented to determine the stress distribution in a simply-supported cylindrical sandwich sector with a functionally graded carbon nanotube core and piezoelectric face sheets subjected to low-velocity impact. The spherical elastic ball hits the top face sheet of the sector at an initial velocity of 50 m/s. The classical non-adhesive elastic contact theory and Hunter's relationship were used to determine the normal contact pressure distribution in terms of time and distance of the contact location. Moreover, Hamilton's principle and Maxwell's static equation were used to obtain the nineteen equations of motion. The numerical code was written to solve these nonlinear equations and the stress components in each layer were calculated in terms of time. In addition, it was assumed that the out-of-shell displacement of the sector at each layer is a quadratic polynomial function of the radial component in addition to a function of the coordinate components within the shell. Due to this assumption, the normal out-of-shell strain is not only zero, or not even a constant, but it changes in the form of a linear function along with the thickness of each layer.

“…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. 41 Further, the influence of hybridization on the compression response of the intra-ply and inter-ply Kevlar–Basalt/polypropylene hybrid cylindrical composites under the high strain rate loading has been investigated in Bandaru et al 42 It is reported that the intra-ply hybrid composites with an alternate weaving of Kevlar–Basalt yarns exhibit high peak stress while compared to inter-ply hybrid composites for the alternate layer of Kevlar–Basalt fibres. Moreover, Ornaghi et al 43 have also studied the effects of stacking sequences and the porosity on the creep behaviour of glass–carbon/epoxy hybrid composites.…”

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.
