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.
Claims16
Cellular material comprising:
- a plurality of component strips, each of said strips having alternate ridge portions and groove portions interconnected by step portions, said strips being arranged in a stacked array with the ridge portions of each component strip facing the groove portions of an adjacent component strip, and means for fastening at least some of said ridge portions to some of said groove portions, at least one of said step portions of each component strip comprising a furrowed step surface having a first end and a second end, a first riser extending upwardly from said groove portion to said first step surface end and being contiguous with said groove portion and said first step surface end, and a second riser extending downwardly from said ridge portion to said second step surface end and being contiguous with said ridge portion and said second step surface end, wherein said cellular material exhibits synclastic behavior and said at least one furrowed step surface facilitates simultaneous expansion and contraction of said cellular material during exhibition of said synclastic behavior.
Cellular material comprising a plurality of cell units each having a substantially cross-shaped cross-sectional configuration, arranged in a matrix array of rows of interconnected cell units, each cross-shaped cell unit being defined by an upper arm, a lower arm, and first and second lateral arms, at least one cell unit of each row having at least one furrowed wall, wherein said cellular material exhibits synclastic behavior and said at least one furrowed wall facilitates simultaneous expansion and contraction of said cellular material during exhibition of said synclastic behavior.
Cellular material as recited in claim the width-to-height ratio being about 1:1.
Cellular material comprising:
- a plurality of component strips, each of said strips having alternate ridge portions and groove portions interconnected by slope portions, said strips being arranged in a stacked array with the ridge portions of each component strip facing the groove portions of an adjacent component strip, and means for fastening at least some of said ridge portions to some of said groove portions, at least one of said slope portions having at least one indentation formed therein, wherein said cellular material exhibits synclastic behavior and said at least one indentation facilitates simultaneous expansion and contraction of said cellular material during exhibition of said synclastic behavior.
