As a first endeavour, nonlinear dynamic response of the glass fibre-reinforced epoxy (GRE) laminated composite
cylindrical shells under an impulse load is investigated based on the first-order shear deformation theory (FSDT)
of shells. Green’s strain and von Kármán hypothesis are assumed to consider the geometrical nonlinearity due
to large deformation in the model. A new solution procedure composed of the differential quadrature method
(DQM) based on the direct projection of the Heaviside function and a non-uniform rational B-spline (NURBS)
based multi-step time integration scheme is employed to discretize the governing equations in the spatial and
temporal domains, respectively. The approach is validated by showing its fast convergence rate and performing
comparison studies with available solutions in the limited available cases. A comprehensive parametric study
is performed then on the model and the effects of the geometrical parameters, number of layers, load location,
time durations, and types of impulse loading on the nonlinear dynamic responses of GRE laminated composite
cylindrical shells are investigated.
