Principios de homogeneização aplicados em uma mistura asfaltica considerada como um compósito elástico

Abstract

Homogenization techniques are useful to simplify methodologies to predict the response of composite solid media, replacing a heterogeneous medium by a macroscopically equivalent homogeneous one. This paper presents the use of homogenization principles for an asphaltic mixture. The approach used herein is a computational framework based on the finite element method using different scales (global e local). It is shown how to predict global elastic parameters using a local analysis. The results indicate great savings in computational effort, making it possible the consideration of the heterogeneity of the material.
