摘要：
Natural materials often boast unusual combinations of stiffness, strength and toughness currently unmatched by today's engineering materials. Beneficially, according to the embodiments of the invention, these unusual combinations can be introduced into ceramics, glasses, and crystal materials, for example by the introduction of patterns of weaker interfaces with simple or intricate architectures. Two-dimensional surface modifications and three-dimensional arrays of effects within these materials allow for the deformation of these materials for increased flexure, impact resistance, etc. Further, the addition of interlocking substrate blocks in isolation or with additional flexible materials provide for improved energy dissipation and toughening. Such modified materials, based on carefully architectured interfaces, provide a new pathway to toughening hard and brittle materials.
