The folded plate structure is a structural form that increases bending rigidity and strength by folding the plate. When plane bent in waves, in-plane stiffness wave orthogonal direction, but extremely decreases because meandering like spring direction. Since shell structures resist external forces mainly forces, it considered there an appropriate arrangement of corrugations according to flow wh...

metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...

Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...

In foaming processes, the blowing agent has a significant influence on material behaviour and necessary processing parameters. Low-density polypropylene foam sheets are usually produced with aliphatic hydrocarbons or alkanes as physical agent. Due to safety precautions environmental impact, there is great interest in using alternative agents such CO 2 . The sole use of often leads corrugation, ...

Perceived depth is conveyed by multiple cues, including binocular disparity and luminance shading. Depth perception from luminance shading information depends on the perceptual assumption for the incident light, which has been shown to default to a diffuse illumination assumption. We focus on the case of sinusoidally corrugated surfaces to ask how shading and disparity cues combine defined by t...
