Free vibration analysis of three-phase CNT/polymer/fiber laminated tow-steered quadrilateral plates considering agglomeration effects
Free vibration analysis of three-phase CNT/polymer/fiber laminated tow-steered quadrilateral plates considering agglomeration effects
This paper introduces a numerical model for predicting the properties of the tow-steered three-phase CNT/polymer/fiber composition. The free vibration of laminated quadrilateral plates is addressed. The behavior of the matrix reinforced with the carbon-nanotube (CNT) additive is calculated based on the Eshelby-Mori-Tanaka micromechanics approach. The approach considers the probable agglomerated CNT phases in the mixture. Every lamina of the laminate is assumed to be constructed by the curvilinear fiber arrangement dipped in the nanocomposite matrix. The fiber placement paths follow smooth orientation angle changing routes. Several homogenization techniques are presented in detail to evaluate the overall properties of the tow-steered three-phase CNT/polymer/fiber laminate. The principle of virtual work based on the first-order shear deformation plate theory is implemented through the NURBS isogeometric analysis method. Some representative results are obtained and compared with those available in the literature to demonstrate the quality of the proposed formulation. The effects of problem variables including the layup, mixture quality, boundary condition, and micromechanical model on the free vibration behavior are investigated by performing parametric studies.

Abstract
This paper introduces a numerical model for predicting the properties of the tow-steered three-phase CNT/polymer/fiber composition. The free vibration of laminated quadrilateral plates is addressed. The behavior of the matrix reinforced with the carbon-nanotube (CNT) additive is calculated based on the Eshelby-Mori-Tanaka micromechanics approach. The approach considers the probable agglomerated CNT phases in the mixture. Every lamina of the laminate is assumed to be constructed by the curvilinear fiber arrangement dipped in the nanocomposite matrix. The fiber placement paths follow smooth orientation angle changing routes. Several homogenization techniques are presented in detail to evaluate the overall properties of the tow-steered three-phase CNT/polymer/fiber laminate. The principle of virtual work based on the first-order shear deformation plate theory is implemented through the NURBS isogeometric analysis method. Some representative results are obtained and compared with those available in the literature to demonstrate the quality of the proposed formulation. The effects of problem variables including the layup, mixture quality, boundary condition, and micromechanical model on the free vibration behavior are investigated by performing parametric studies.
