Flexural response of MWCNT-reinforced composite plate

Flexural response of MWCNT-reinforced composite plate Flexural response of artificial fibre-reinforced laminated composite plate is presented by efficient 2D shear deformation theory consisting of algebraic in conjunction with hyperbolic tangent and cosine functions. To eliminate unknowns, the condition of stress-free top and bottom surfaces is enforced in the present model. The present 2D mathematical model has been formulated using present novel theory. To make present model compatible with commercial software displacement continuity implemented in 2D finite element (FE) formulation of the present novel hyperbolic shear deformation theory, in-house MATLAB code has been developed for 2D FE formulation of the present theory. Multiwalled carbon nanotubes (MWCNT) fillers is used as reinforcement. The rule of mixture method along with the Halpin–Tsai micromechanical model is employed to calculate the material properties of the nanocomposite matrix. The need of shear correction factor was eliminated owing to realistic parabolic shear strain profile. The accuracy of the present 2D model compared with existing literature 3D works and found to be in good coherence. Hence, 2D present model was found to be robust enough in predicting results close to 3D solutions. Parametric studies were performed for a comprehensive assessment of the effect of varying the layer schemes, boundary conditions, aspect ratio, and thickness ratio on displacements and stresses of the plate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Asian Journal of Civil Engineering Springer Journals

Abstract

Flexural response of artificial fibre-reinforced laminated composite plate is presented by efficient 2D shear deformation theory consisting of algebraic in conjunction with hyperbolic tangent and cosine functions. To eliminate unknowns, the condition of stress-free top and bottom surfaces is enforced in the present model. The present 2D mathematical model has been formulated using present novel theory. To make present model compatible with commercial software displacement continuity implemented in 2D finite element (FE) formulation of the present novel hyperbolic shear deformation theory, in-house MATLAB code has been developed for 2D FE formulation of the present theory. Multiwalled carbon nanotubes (MWCNT) fillers is used as reinforcement. The rule of mixture method along with the Halpin–Tsai micromechanical model is employed to calculate the material properties of the nanocomposite matrix. The need of shear correction factor was eliminated owing to realistic parabolic shear strain profile. The accuracy of the present 2D model compared with existing literature 3D works and found to be in good coherence. Hence, 2D present model was found to be robust enough in predicting results close to 3D solutions. Parametric studies were performed for a comprehensive assessment of the effect of varying the layer schemes, boundary conditions, aspect ratio, and thickness ratio on displacements and stresses of the plate.
