Abstract

In this paper, the homogenization approach was
presented to predict the effective mechanical properties of heterogeneous materials such as composite
materials. Indeed, the main idea
of this approach is to characterize the effective mechanical properties from a
microstructural description of the heterogeneous materials and the knowledge of
the local behavior of constituents using the homogenization process. It is a
very efficient tool which is intensively developed
in the field of numerical simulation of heterogeneous materials. Different scheme
established from the solution of Eshelby’s inclusion
problem are recalled such as Mori-Tanaka scheme, dilute scheme and Voigt and
Reuss bounds. Homogenization approach was applied to estimate the effective
mechanical properties of tungsten fiber reinforced bulk metallic glass matrix
composite. Predicted values were confronted with those obtained by experimental
approach from literature. These comparisons show good agreement between the
predicted and experimental values. The maximum deviations remain lower than
10.5% using Voigt bound. A parametric study shows that the mechanical
properties depend strongly on the shape of inclusions.
