description: The main goal of this study is using analytical solution to investigate the nonlinear dynamic response and  vibration of sandwich auxetic composite cylindrical panels. The sandwich composite panels have three  layers in which the top and bottom outer skins are isotropic aluminum materials, the central auxetic  core layer – honeycomb structures with negative Poisson’s ratio using the same aluminum material. The  panels are resting on elastic foundations and subjected to mechanical, blast and damping loads. Based  on Reddy’s first order shear deformation theory (FSDT) with the geometrical nonlinear in von Karman  and using the Airy stress functions method, Galerkin method and 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 Winkler and Pasternak foundations, mechanical,  blast and damping loads on the nonlinear dynamic response and the natural frequencies of sandwich  composite cylindrical panels are studied.
