Flexure Investigation of P-FG-Plates Via Integral Quasi-3D Theory with Considering Imperfection in the Material Composition

Abstract

The flexural response of imperfect advanced (functionally graded) composite plates was considered by using an integral-quasi-3D shear deformation (quasi-3D-HSDT) model. The impact of transverse and normal strains was integrated. The present formulation has four displacement variables-unknowns only. The defect in the material composition is taken into consideration based on the power law gradation. The four differential governing equations are extracted with the help of the virtual work principle (VWP) and Navier’s method. A range of numerical results were presented in the table and graphs forms to reveal the impact of the inhomogeneity parameter, the imperfection, the dimensions and geometric ratios on the static (flexure) response of imperfect advanced composite plates. The work most significant accomplishment was the presentation of a simple theoretical model based on a problem with the material makeup of functionally graded materials.
