In the present study, modelling and vibration analysis of Carbon nanotubes/ fiber/ polymer composite microplates are investigated. The governing equations of the Carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. The modified couple stres...

The effect of fibre bundling on the effective transverse properties of unidirectional fibre composites has been investigated by way of finite element method and micromechanics models of fibre bundles. Based on the micromechanical model of single-fibre composites, plane strain models for composites reinforced by fibre bundles are presented. The effective elasto-plastic stress /strain behaviour w...

The integrity of tunnel structures deployed in difficult geological conditions such as expansive soils can be improved by incorporating compressible layers the lining. Such lining materials obtained embedding weak inclusions (Expanded polystyrene, Expanded glass beads, Air voids) into a cement paste material. material properties these individual constituents well their geometry affect overall b...

effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. an embedded carbon nanotube  in  a  polymer  matrix  and  its surrounding  interphase  is  replaced with an equivalent fiber for  predicting  the  mechanical  properties of  the  carbon  nanotube/polymer composite. the effects of an interphase layer between the nan...

Results from fatigue experiments done on a SiC/SiC composite are presented. A micromechanics-based model is used to study the observed behavior under cyclic loading. The includes consideration of progressive damage, creep and oxidation fiber matrix. Comparison predictions with test data showed that deformation during in this material explained primarily by damage form matrix microcracking inter...

A novel approach for the micromechanics analysis of composite structures is developed using refined beam models and the mechanics of structure genome (MSG). The MSG provides a tool to obtain the complete stiffness matrix of general composite materials by asymptotically minimizing the loss of information between the original heterogeneous body and the sought homogenized body. The constitutive in...
