Dynamic response of porous functionally graded sandwich nanoplates using nonlocal higher-order isogeometric analysis

The main goal of this work is to indicate the dynamic response of sandwich nanoplates with a porous functionally graded (PFG) core using isogeometric analysis (IGA) based on the higher-order shear deformation theory (HSDT) with different continuous functions f(z). The small-scale effect appearing in nanostructures is included by employing the nonlocal elasticity theory. The sandwich nanoplate consists of three layers: the metal bottom layer, the ceramic top layer, and the core layer being PFG materials with the log-uneven porosity distribution. The convergence and reliability of the proposed method are verified by comparing obtained numerical results to those of other published works. Moreover, some examples are conducted to examine the impact of parameters on the dynamic response of sandwich nanoplates with the PFG core. © 2022 Elsevier Ltd
