Effects of lattice stiffeners on the nonlinear behavior of variable-curvature FG-GRC panels subjected to blast and step loads
This paper presents a semi-analytical investigation of the nonlinear dynamic responses of lattice-stiffened variable-curvature functionally graded graphene-reinforced composite (FG-GRC) sandwich panels with a porous core under impulsive loading conditions. The structure consists of FG-GRC face sheets and a lightweight...
