Optimizing an "improper" combination, a combination consisting of an even plate or shell and a conceptually irregular set of reinforcing stiffeners, enables to attain said combination's hitherto unknown unique synergetic attribute, the attribute of total disappearance of local buckling phenomena of said combination when compressing thereof up to destruction of structural material(s) thereof, and therefore enables to utilize strength potentialities of the material per se utterly, just us utterly as when stretching thereof, and besides irrespective of plates/shells shape and size, irrespective of structural materials' kind, volume and weight, and irrespective of operational temperatures and type of external load distribution, etc. Accordingly, given equal other conditions, cardinal weight reduction or bearing capacity's raise of thin-walled structure's bearing skin is attainable that can be utilized for any aerospace thin-walled structure, very extensively in naval engineering, and in civil engineering sometimes also; besides a reduction of expenditures, more efficient utilization of energy resources and hence enhancement of the environment of mankind is provided too. I call said synergic attribute "Superstability". |
