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

Roberto Martins da Silva Décio Jr, Leslie Darien Pérez-Fernández, Julián Bravo-Castillero

Resumo


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