Abstract
Cellular material formed from a plurality of component strips each comprising alternate ridge portions and groove portions interconnected by step portions, the step portions comprising a first riser, a second riser, and a furrowed step surface. The furrowed step surface has at least one indentation formed therein, preferably two oppositely-directed semicircular indentations. The resulting interconnected array of substantially identical cell units defines a sheet of cellular material exhibiting highly synclastic behavior. In an alternate embodiment, the step portion is replaced by a slope portion having at least one semicircular indentation formed therein. A method of fabrication of the novel cellular material is also provided.
