Abstract

A composite granular structure, which enables forced energy confinement and disintegration of impulses propagating in a laminar granular medium and fabrication methods for said structure. The granular structure comprises an array of composite chains of alternating high-modulus, rigid beads and lower modulus, soft beads in a supporting matrix.
