Three-scale homogenization procedure is proposed in this paper to provide estimates of the effective thermal conductivities of porous carbon-carbon textile composites. On each scale the level of fiber tow (micro-scale), the level of yarns (meso-scale) and the level of laminate (macro-scale) a two step homogenization procedure based on the Mori-Tanaka averaging scheme is adopted. This involves e...

In this study, an artificial neural network is designed and trained to predict the elastic properties of short fiber reinforced plastics. The results finite element simulations three-dimensional representative volume elements are used as a data basis for network. fraction, length, matrix-phase properties, orientation varied so that can be within very wide range parameters. A comparison predicti...

The present paper aims at computational simulations of particle reinforced Metal Matrix Composites as well as parts and specimens made thereof. An incremental Mori-Tanaka approach with isotropization of the matrix tangent operator is adopted. It is extended to account for large strains by means of co-rotational Cauchy stresses and logarithmic strains and is implemented into Finite Element Metho...

Eshelby's theory is the foundation of composite mechanics, allowing calculation of the effective elastic moduli of composites from a knowledge of their microstructure. However, it ignores interfacial stress and only applies to very dilute composites-i.e. where any inclusions are widely spaced apart. Here, within the framework of the Mori-Tanaka multiphase approximation scheme, we extend Eshelby...

We have used the Mori–Tanaka method to study the effect of nonlinear interface debonding on the constitutive behavior of composite material with high particle volume fraction. The interface debonding is characterized by a nonlinear cohesive law determined from the fracture test of the high explosive PBX 9501. Using the example of the composite material with spherical particles subject to hydros...
