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. date: 2017 date_type: published publisher: Elsevier full_text_status: public publication: Aerospace Science and Technology volume: 70 pagerange: 396-404 refereed: TRUE issn: 1270-9638 related_url_url: https://doi.org/10.1016/j.ast.2017.08.023 citation: Nguyen, Dinh Duc and Kim, Seung-Eock and Ngo, Duc Tuan and Tran, Phuong (2017) New approach to study nonlinear dynamic response and vibration of sandwich composite cylindrical panels with auxetic honeycomb core layer.
