A material and an article comprising the material are presented. The material
comprises
a plurality of structural components. The structural components are configured
in a series of increasing structural component size classes. The series has a base
unit size class and at least one modular size class, and a component of the at
least one modular size class comprises a plurality of components of the next smaller
size class in the series. The structural components of the base unit size class
comprise at least one bulk phase, and the structural components are bonded together
at interfaces. Mechanical damage originating within a modular size class structural
component is energetically favored to propagate in a distributed fashion among
the plurality of structural components contained within the modular size class
structural component.
