Abstract:
1. A multiple layer composite apparatus configured to protect an object, the multiple layer composite apparatus comprising: at least one cell configured to redistribute at least one applied load, the at least one cell comprising: a first planar layer with a first material, wherein the first planar layer is configured to receive the at least one applied load in at least one applied load area; a second planar layer with a second material and a second fracture toughness, wherein the first material differs from the second material; and at least one structurally robust arched plate operatively connected to and disposed between the first and second planar layers configured to disperse energy created by the at least one applied load; wherein the at least one arched plate is corrugated and defined by at least one first arch and at least one second arch; and wherein the at least one first arch is operatively connected to and overlaid with the first planar layer and the at least one second arch is operatively connected to and overlaid with the second planar layer so that a contact-induced nonlinear deformation results between the arches and the first and second planar layers upon receipt of the at least one applied load.
