Transient response of GPLs reinforced FG-porous skewed plates subjected to blast loading

Abstract

The present study investigates the transient response of graphene nanoplatelets (GPLs) reinforced functionally graded (FG) porous skewed plates subjected to blast loading. The plates are assumed to be made of Aluminium which is reinforced with graphene nanoplatelets. The effective elastic modulus and density of reinforced plates are determined by Halpin-Tsai and Voigt models, respectively. The pores are embedded throughout the volume of the plates employing symmetric and asymmetric distributions followed by certain functions. The fundamental equations are developed employing Euler-Lagrange’s equation in the framework of C0-continuous higher-order shear deformation theory. The numerical results are accessed using the finite element method and the Newmark technique is adopted to achieve a transient response of the above-mentioned plates. The influence of parameters such as porosity coefficient, GPLs weight fraction, and skew angle on the transient response of the GPLs reinforced FG-porous plates with all edges clamped and simply supported boundary conditions is demonstrated.
