Uniaxial Compression of 2d Packings of Cylinders. Effects of Weak Disorder

Abstract

We study uniaxial compression of 2d-ordered packings of parallel cylinders, which present weak geometrical defects responsible for a heterogeneity of the spatial distribution of intergranular stresses. The strongest stresses form links which generate an irregular network. By creating different types of vacancies, we show the importance of that network.
