an aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation) direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation) direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometr...

abstract one of the most frequently encountered cases of rapid varied flow is the hydraulic jump. it occurs when a supercritical open channel flow changes into sub critical flow. in the present research, the experimental study of the hydraulic jump on seven sinusoidal corrugated beds with different wave steepness. the wave steepness of sinusoidal corrugated beds is in the range of 0.1667 to 0.7...

In this study the effects of corrugated absorber plate and using aerosol-carbon black nanofluid on heat transfer and turbulent flow in solar collectors with double application and air heating collectors, were numerically investigated. The two-dimensional continuity, momentum and energy equation were solved by finite volume and SIMPLE algorithm. In the present investigation all the simulations w...

We present a novel method for fabricating carbon fiber composite sandwich panels with lattice core construction by means of electrical discharge machining (EDM). First, flattop corrugated carbon fiber composite cores were fabricated by a hot press molding method. Then, two composite face sheets were bonded to each corrugated core to create precursor sandwich panels. These panels were transforme...

Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated beams, thick plates the flanges thin sinusoidal sheets web, elements can be joined by standard bolted end-plate connections. In case thin-walled only, additional are required to accommodate shape position...

In this work, an analytical study on the bending stiffnesses of corrugated board has been performed. Formulations to calculate the bending stiffnesses D11, D22, D12, and D66 of the equivalent plate representing the corrugated board have been established, and then compared to expressions suggested by other investigators. Several methods for modeling the shape of the corrugated orthotropic medium...

In the title compound, C12H15NO4, the dihedral angle between the acetamide group and the ring is 29.6 (2)(su?)°. In the crystal mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen bonds, thereby forming corrugated sheets propagating in the ac plane. These sheets are composed of R4(4)(28) graph-set motifs.

The falling film flow characteristics of a liquid on the surface corrugated sheet packing are crucial for its mass transfer performance in various industrial applications. In this study, experiment with laser-induced fluorescence technology was conducted to validate simulated using computational fluid dynamics (CFD). influences Reynolds number (Re) and structure were analyzed quantitative thick...

Abstract Currently, corrugated cold-formed steel sheets are widely used as parts of cladding panels and roof envelopes in public residential buildings. However, the design is weakly covered by current building codes. This paper investigates load-bearing capacity with sinusoidal profile, presenting results experimental research that was performed GRISPE project at Research Center for Steel, Timb...
