Abstract
A composite modular energy absorbing assembly with one or more gamma structures that are interposed with one or more delta structures . The gamma structures have a base ′ and a plurality of recesses ′ defined therewithin. The recesses ′ have at least one wall ′ extending from the associated base ′. At least some of the recesses ′ are oriented such that their walls are substantially parallel to a major incident component of an impacting force. The walls ′ collapse. The delta structures have a lattice of interconnected strands which intersect to define a plurality of cells . The plane of at least some of these cells are substantially parallel to the impacting force. The lattice collapses during energy absorption. The composite assembly serves to decelerate an object that impacts thereupon in order to maximize energy absorption over a given distance. In alternate embodiments, stacking arrangements include: gamma structures alone; or delta structures alone.
