In the implementation of Carbon Nanotube Reinforced Polymer matrix Composites in structural applications, deflection and stress analysis are important considerations. In the present study, a multi scale analysis of deflection and stress analysis of carbon nanotube (CNT) reinforced polymer composite plates is presented. A micromechanics model based on the Mori-Tanaka method is developed by intro...

The strong–property–fluctuation theory (SPFT) provides a general framework for estimating the constitutive parameters of a homogenized composite material (HCM). We developed the elastodynamic SPFT for orthotropic HCMs, in order to undertake numerical studies. A specific choice of two–point covariance function — which characterizes the distributional statistics of the generally ellipsoidal parti...

This paper is devoted to the buckling analysis of thin composite plates under straight single-walled carbon nanotubes reinforcement with uniform distribution and random orientations. In order to develop the fundamental equations, the B3-Spline finite strip method along with the classical plate theory (CPT) is employed and the total potential energy is minimized which leads to an eigenvalue prob...

The linear strong–property–fluctuation theory (SPFT) was developed in order to estimate the constitutive parameters of certain homogenized composite materials (HCMs) in the long–wavelength regime. The component materials of the HCM were generally orthorhombic mm2 piezoelectric materials, which were randomly distributed as oriented ellipsoidal particles. At the second–order level of approximatio...

Using aMarx-oscillator standing-wave resonancemethod, we measuredthe internal friction &' of sintered titanium containing up to 26 volume-percent voids (c). The surprising &I-versus-c curve shape, an exponential increase, lead us to remeasure &I-versus-c by acoustic-resonance spectroscopy, which gave similar results. We hypothesized that both void shape and void size change with c. For the void...

Carbon Nanotubes reinforced composite materials are widely used in aerospace engineering due to high strength-to-weight ratios, which can be tailored per requirements. The behaviour of the structures depends on various factors like, Lamination scheme, Ply orientation and loading conditions. In present work, Static deflection stresses analysis a Nano Tube laminated hybrid plate extends First Ord...

The present work aims at determining the effective thermal conductivity of two- or three-dimensional composites with imperfect interfaces between their constituent phases. These are described by highly conducting, lowly conducting general model. To achieve objective, classical Hill-Mendel lemma is first extended to include effects and an equivalent inclusion method (EIM) proposed. basic idea EI...
