MODELING OF MECHANICAL BEHAVIOUR OF A 1D, LINEAR AND MICROPERIODIC COMPOSITE, WITH FAILURE, VIA THE ASYMPTOTIC HOMOGENIZATION METHOD

Abstract

In this paper the Asymptotic Homogenization Method is combinedwith a model of Hyperelasticity with softening (wich models the mechanical failureof the material), with the purpose of estimating the mechanical behaviour ofmicroperiodic composites in the way to reproduces better the behaviour obtainedin experiments, found in the literature. This hybrid approach brings somesatisfactory results, showing that the (hypothetical)composite studied presentseffective behaviour very close to the expected from the Hyperelasticity model. Thatis a very important fact because can be used as a tool to predict the failure ofcomposite materials, trough its constituent materials informations. This evaluatingneeds more steps, to be possible much bigger and strong conclusions, however theresults obtained until now seems like very promissory.
