Genetic Programming has been used to determine Chèzy resistance coefficient for full circular corrugated channels. Three corrugated plastic pipes have been experimentally studied in order to generate data. The tests aim at measuring hydraulic parameters of the open-channel flow for some slopes, from 3.49–17.37% (2–10°), in order to discover the dependence of the channel resistance coefficient w...

In this study, fire resistance tests were performed on a conventional slim floor beam and a prestressed composite beam with corrugated webs, which is suitable for a long-span structure with a reduction in story height by utilizing the prestress and accordion effect. In the fire test program, the ISO 834 standard fire curve was adopted. Key test variables were the effect of prestress, shape of c...

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...

For corrugated pipes with a square groove, it is known that there no interaction between the main flow and groove when aspect ratio less than four. When length height are different, occurs in pipe. In previous studies, was investigated whether this dependent on length. However, changing height, shape of vortex generated inside changes, which may cause to occur. Therefore, paper both as well pit...

This work is focused on the finite element study of the energy absorbing behavior of aluminum (corrugated webs). The aim is to study the mechanism of energy absorption in specific metallic structures by understanding these mechanisms. The sine wave web (or corrugated web) structural component constructed of aluminum has been chosen as the specific structural element for this study. The sine wav...

We experimentally observe the excitation of dark multipolar spoof localized surface plasmon resonances in a hybrid structure consisting of a corrugated metallic disk coupled with a C-shaped dipole resonator. The uncoupled corrugated metallic disk only supports a dipolar resonance in the transmission spectrum due to perfect symmetry of the structure. However, the dark multipolar spoof localized ...

Strong competition and the high demands of consumergoods companies for just-in-time delivery together with high standards of product and service quality are turning the top end of the corrugated-board box market into a very tough place to be. Customers order a large variety of different boxes, each with its own colour scheme and product specific printing, and expect them to be delivered at very...

Interface states can always arise in heterostructures that consist of two or more (artificial) materials with topologically different energy bands. The gapped band structure can be classified by the Chern number (a topological invariant) generally or the Zak phase in one-dimensional periodic systems. Recently, topological properties have been employed to investigate the interface states occurri...

This paper will explore the technology behind corrugated model morphing wings and their potential benefits to society. The two major models of corrugated morphing wings will be examined and explained. In order to provide background, the technology and shape behind all morphing wings will also be examined. The applications of these wings will then be explored. Using data from wind tunnel testing...
