This paper studies surface gravity waves in a channel with corrugated sidewalls in water of constant depth according to linear theory. Waves propagating along the channel encounter a nite patch of step-like corrugations in one of the channel walls. The method of solution employed is one of expansion in terms of eigenfunctions in each region and matching at the boundaries between regions. It is ...

Bamboo weaving is an intangible cultural heritage in China. Exploring people’s aesthetic preferences for bamboo patterns to better serve the design of architectural decoration can help promote upgrading traditional crafts. This study explored differences between genders oculomotor indicators different through eye-movement experimental combined with a subjective questionnaire explore whether hav...

The use of corrugated webs in steel beams has become one the most practical ways to increase efficiency resisting loads, natural frequencies, and their resulting displacements. Such a practice benefit achieving same as with flat web greater thickness. Consequently, effect types on flexure mode shapes frequencies been investigated by analyzing 23 using finite element (FE) numerical analysis tech...

We numerically simulate the transport of elliptic Janus particles along narrow two-dimensional channels with reflecting walls. The self-propulsion velocity of the particle is oriented along either its major (prolate) or minor axis (oblate). In smooth channels, we observe long diffusion transients: ballistic for prolate particles and zero diffusion for oblate particles. Placed in a rough channel...

This paper investigates the relationship between mechanical behaviors and shape of corrugated fiberboard by means of buckling analysis, which is done by FEM (Finite Element Method). Firstly, after analyzing the structure of corrugated fiberboard a single-wall corrugated fiberboard model was built. The buckling load was measured in the ideal condition by linear buckling analysis (eigenvalue buck...

The depth average module of NASIR finite volume solver was applied to study the tide induced currents in Khowr-e-Musa estuary. The model computes water level variation and velocity components in horizontal plane solving depth average continuity and momentum equations considering the hydrostatic pressure distribution. The software takes into account the bed and wall geometric complexities and re...

Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web gird...
