Granular templating: Effects of boundary structure on particle packings under simultaneous shear and compression

We present our findings on the effect of various confining substrates, both crystalline and amorphous, on spherical particles, packed under gravity followed by the simultaneous application of shear and compressive strains. We treat the voids and particles of the substrates interchangeably by identif...

Description
Summary:We present our findings on the effect of various confining substrates, both crystalline and amorphous, on spherical particles, packed under gravity followed by the simultaneous application of shear and compressive strains. We treat the voids and particles of the substrates interchangeably by identifying the primitive unit cell for each, and use radial and angular distribution functions to determine the packing structures. We show that a substrate templated with a 2D square lattice, for which void and particle packing structures are identical, is most suitable for inducing crystallisation mimicking the substrate structure.
