Abstract:
1. A material comprising: a plurality of structural components bonded together at interfaces, each structural component having a characteristic length, said components configured in a plurality of structural component size classes, wherein each structural component belonging to an exemplary size class has a characteristic length that is within 25% of a mean characteristic length calculated for all structural components of the exemplary size class, and wherein each size class has a unique mean characteristic length; wherein a base unit size class has the smallest mean characteristic length of all structural component size classes, and wherein said structural components of said base unit size class comprise at least one bulk phase; wherein any structural component size class that is not said base unit size class is a modular size class, and wherein a structural component of an exemplary modular size class comprises wherein interfaces bonding together structural components of an exemplary modular size class require more energy to propagate mechanical damage than interfaces bonding together structural components contained within structural components of said exemplary modular size class.
