Superstability of thin-walled structures

a thin-walled structure, super-stability technology, applied in envelope/bag making machinery, paper/cardboard containers, other domestic articles, etc., can solve the problem of inability to achieve the potential inherent strength capability of structural materials, inability to deformation and follow destruction, and inability to accept deformation and subsequent destruction, etc. problem, to achieve the effect of minimal weight and necessary strength, the aerospace industry faces a perennial and even acute problem of thin-walled construction

AI Technical Summary

Benefits of technology

The technical effect that this new structure solves by reducing its size while still maintaining their original shape even at high tensile stress levels without losing it permanently. It also has better load carrying capabilities than previous designs with lesser durabilities.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the performance of thin weldings made of metals called martensites because they provide better mechanical support compared to traditional metal constructions. These compositions require careful consideration during manufacturing processes, particularly considering their maximum stress capabilities. To address these issues, specialist organizations conduct extensive simulations overall, including those seeking new designs based upon previous experience rather than objective criteria alone.

Embodiment Construction

[0037] The stiffened thin plates (panels) of the same constant thickness each, shown in FIGS. 1P and 1S, are of the same homogenous material, of the same overall dimensions, of the same weight and both are reinforced in the direction of uniform compressing by the use of the same number of the same identical parallel stringers of simplest (rectangular) uniform cross section.

[0038] The prior-art panel, shown in FIG. 1P, is fitted up (reinforced) with a set of identical equidistant stringers, i.e. with a regular stringer set. If material's amount isn't too much excessive for given overall dimensions or if overall dimensions are big enough for given materials' amount, such a panels certainly lose the stability when compressed rather strongly and thus material's utmost strength capability remains idle. This capability can be utilized better by means of optimization within given plate's size, kind of material and its amount. The best combination of panel's variable parameters', i.e. an optim

Abstract

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".
