    Carbon nanotube-mullite (Al2O3/SiO2=3/2) composites have been prepared by hot-pressing the corresponding composite powders, in which the multi-walled carbon nanotubes(1~10 vol%) are homogeneously dispersed between the mullite grains. The microstructure of the specimens has been studied and discussed in relation to the properties of the matrix, the bending strength and the fracture Cited by: 2. 3D microstructure of particle reinforced metal matrix composites.

This work is concerned with modeling the nonlinear mechanical deformation of composites comprised of a periodic microstructure under small displacement conditions at elevated temperatures. The practical motivation for such work stems from the need to design and optimize new multiphase materials and to predict their micromechanical and bulk Cited by: Estimate of overall elastic module of a body with ellip- cal or ellipsoidal inclusions or voids, soidal inclusions or voids.

The theoretical background of the method is recalled first. Two different families of numerical methods are considered to solve the problem. The first is based on the Finite Element by: Micromechanics allows to predicting multi-axial properties that are often difficult to measure experimentally.

A typical example is the out-of-plane properties for unidirectional composites. The main advantage of micromechanics is to perform virtual testing in order to reduce the cost of an experimental campaign. Indeed, an experimental.

The subject of this book is the computational analysis of interrelations between mechanical properties (e.g., strength, damage resistance stiffness) and microstructures of composites. The methods of mesomechanics of composites are reviewed, and applied to the modelling of the mechanical behaviour of different groups of composites.

Huang et al. [38] proposed a topology optimization method to design unit cellular materials and composites with periodic microstructure to achieve maximum stiffness. Chen et al. [39] investigated. Key words: Metal matrix composites, TiC, Infiltration, microstructure, flux, mechanical strength.

composite is lost and micromechanical analyses of periodic composites are no longer applicable. The present paper summarizes a series of investigations in which the behaviour of periodic composites with several types of localized effects have been analysed and predicted.

In general, these analyses are based on the combination of three approaches. composites have been extended to the viscoelastic case. How­ ever, no theory has been developed for linear viscoelastic solids with periodic microstructure, even though many results are available for the elastic case (Nemat-Nasser and Taya,; Nemat-Nasser et File Size: 2MB.
