Corrugation

Corrugation

 

the formation of corrugations (bends or waves) on sheets of ferrous and nonferrous metals, asbestos cement, cardboard, or fabric in order to increase the materials’ stiffness under conditions of bending or compression strains. Rounded corrugations are most often used; trapezoidal, triangular, and more complicated forms are less frequent. Corrugation is performed on presses (by molding) or between shaped rolls (by rolling). Corrugated materials are widely used in construction, the aircraft industry, and other branches of engineering.

However, the corrugation shape used in Zhang's study is triangular, although it was reported that only the pressure drop will be affected by the corrugation shape and not the heat transfer rate (Kanaris et al.
As shown by further investigations, the more extensive occurrence of constrictions and corrugation in the ledeburitic steel in comparison with other steels is determined by the thermophysical properties of these materials.
Nevertheless, the pipe invert remained in good condition, reflecting only a few minor "dents" on the leading edge corrugation.
It is well known that many factors affect the emergence and development of rail corrugation; different corrugation has different mechanisms, and it is difficult to use one method to completely cure rail corrugation [8-11].
Previous work was conducted by [3] in order to numerically study the effect of the corrugation angle and the aspect ratio h / w of the three-dimensional flow and heat transfer in a triangular base channel simulating a corrugated plate heat exchanger.
MS-to-CPS balun section and Fermi-Dirac tapered radiators with corrugation. Simulation results demonstrate high gain, symmetrical radiation patterns, narrow beamwidth, and low sidelobe levels for whole frequency ranges from 70 to 110 GHz and above.
The corrugation angles were 30[degrees],60[degrees], and combination of 30[degrees] and 60[degrees].
(2009) used ASHRAE Standard 120 to obtain pressure loss data for one particular corrugation configuration.
Standard pipe corrugation uses a continuous chain of mold blocks mounted on one or two oval tracks to vacuum form a continuously extruded tube or parison.

The application of corrugation to ordinary structures started with webs on the basis of aeronautic findings in 1924, and it has been used in ordinary steel structures since early 1960s [1].
The main reasons of unconventionally complicated load-bearing behaviour of such panels are: a complicated geometry that includes the transverse corrugation, an effect of cold deformation on the materials properties of the panel and, possibly, the complex loads during the service life of the structure.
