Multi-directional load dissipation using multimaterial mechanical metamaterials

A multimaterial mechanical metamaterial (MMM) system, comprising:

• a top surface positioned at a top side of the MMM system;
• a bottom surface positioned at a bottom side of the MMM system;
• a left structure positioned at a left side of the MMM system and comprising four left lateral faces defining a left open-ended prism shape;
• a right structure positioned at a right side of the MMM system and comprising four right lateral faces defining a right open-ended prism shape;
• a middle structure positioned between the left structure and the right structure and comprising four middle lateral faces defining a middle open-ended prism shape;
• a left bar extending between a left edge and a right edge of the left open-ended prism shape of the left structure;
• a right bar extending between a left edge and a right edge of the right open-ended prism shape of the right structure;
• and
• a middle bar extending between a top edge and a bottom edge of the middle open-ended prism shape of the middle structure,
• wherein the top surface, the bottom surface, the left structure, the right structure and the middle structure comprise a first material, and the left bar, the right bar and the middle bar comprise a second material that is more elastic than the first material,
• wherein upon a compressive load on the MMM system, the left bar and the right bar are configured to dissipate a first portion of the compressive load to an orthogonal direction of the compressive load, and the middle bar is configured to reverse a second portion of the compressive load in an opposite direction of the compressive load.
