Forced vibration of functionally graded sandwich plates with surface irregularities under moving vehicle loads on elastic foundations

Chebyshev finite element method for dynamic analysis of functionally graded sandwich plates lying on an elastic foundation subjected to harmonic loading

This study presents a Chebyshev finite element method (C-FEM) for the dynamic analysis of functionally graded sandwich (FGS) plates lying on an elastic foundation (EF) and subjected to harmonic loading (HL). The FGS plate consists of two functionally graded (FG) face sheets and either a hard-core (Type 1) or a soft-cor...

Nonlinear transient response analysis of FGM sandwich structures with stepped face sheets

Nonlinear combined resonances of FGM stepped sandwich plates under transverse and axial excitations

This paper addresses the nonlinear vibration problem of variable-thickness functionally graded structures and presents the first systematic investigation on the combined resonance characteristics and chaotic dynamic behavior of functionally graded material (FGM) stepped sandwich plates under combined transverse and axi...

An analytical study on static, free vibrational and buckling behaviour of FG-GNPRC plates using nonpolynomial shear deformation theory

This study presents an analytical formulation based on the inverse hyperbolic shear deformation theory (IHSDT), a non-polynomial higher-order shear deformation theory, for the static, buckling, and free vibration analyses of functionally graded graphene nanoplatelets reinforced composite (FG-GNPRC) plates. The IHSDT sa...

Experimental and semi-analytical investigation of dynamic behavior of sandwich plates with porous core and CFRP face sheets

This paper presents an experimental and theoretical investigation of the vibration behavior of sandwich plates consisting of an Expanded Polystyrene (EPS) porous concrete core and carbon fiber-reinforced polymer (CFRP) face sheets. For the theoretical study, Reddy’s third-order shear deformation theory (RTSDT), combine...

Free Vibration Analysis and Experimental Validation of Sandwich Plates with Hollow Tetrahedral Truss Cores

This study investigates the free-vibration behavior of sandwich plates with hollow tetrahedral truss cores and evaluates the capability of an equivalent-continuum model to predict their global natural frequencies. An integrated analytical, numerical, and experimental methodology was adopted. A shear-deformable plate fo...
