%T Dynamic response and vibration of composite double curved shallow shells with negative Poisson’s ratio in auxetic honeycombs core layer on elastic foundations subjected to blast and damping loads
%X The purpose of the present study is to investigate dynamic response and vibration of composite double curved
shallow shells with negative Poisson’s ratios in auxetic honeycombs core layer on elastic foundations subjected
to blast and damping loads using analytical solution. This study considers composite double curved shallow
shells with auxetic core which have three layers in which the top and bottom outer skins are isotropic aluminum
materials; the central layer has honeycomb structure using the same aluminum material. Based on the first order
shear deformation theory (FSDT) with the geometrical nonlinear in von Karman and using Airy stress functions
method, Galerkin method and the fourth-order Runge–Kutta method, the resulting equations are solved to obtain
expressions for nonlinear motion equations. The effects of geometrical parameters, material properties, elastic
foundations Winkler and Pasternak, the nonlinear dynamic analysis and vibration of double curved shallow shells
with negative Poisson’s ratios in auxetic honeycombs core layer are studied
