Free vibration analysis of laminated composite porous plate

Free vibration analysis of laminated composite porous plate In the present work, the free vibration response of laminated composite porous plates explored using improved cubic shear deformation theory.

A 2D finite element model developed for the present mathematical model to analyse the fundamental frequency of the porous plate. Due to the interface shear stress continuity of individual layers, the improved third-order shear deformation theory depicts better results than the first, second, and third-order theories.

Abstract

In the present work, the free vibration response of laminated composite porous plates explored using improved cubic shear deformation theory. It is the first attempt to analyse vibration analysis of the laminate using this advanced theory. In this theory, transverse shear stress continuity incorporated at the interface of each laminate in conjunction with free surface consideration at the plate top and bottom. The different types of porosity distribution introduced in the entire thickness of the plate. A 2D finite element model developed for the present mathematical model to analyse the fundamental frequency of the porous plate. Due to the interface shear stress continuity of individual layers, the improved third-order shear deformation theory depicts better results than the first, second, and third-order theories. An in-house FORTRAN code developed for the present study by the authors. The effects of different orientation angles, boundary conditions, and material properties on the fundamental frequency were investigated with different numerical examples. The convergence study was conducted to determine the stability and accuracy of the present model. The results in comparison with the literature found to agree well.
