Abstract Generalizing the first-order shear deformation plate theory (FOPT) proposed by Ambartsumyan (Theory of anisotropic plates, Nauka, Moscow, 1967 ( in Russian )) to heterogeneous laminated nanocomposite plates and nonlinear vibration problem is analytically solved taking into account an elastic medium this study for first time. The Pasternak-type foundation model (PT-EF) used as model. Af...

Martin Josefsson [1] has coined the term ‘bisect-diagonal quadrilateral’ for a quadrilateral with at least one diagonal bisected by other diagonal, and extensively explored some of its properties. This also been called ‘bisecting [2], ‘sloping-kite’ or ‘sliding-kite’ [3], ‘slant kite’ [4]. The purpose this paper is to explore more properties quadrilateral.

Ring-On-Ring (ROR) tests have been widely applied to evaluate the biaxial flexural strength of brittle materials. Properly designed geometry specimens and loading configurations are essential for accurate test results. In this paper, stress distribution round glass plates subjected between concentric rings was investigated via finite element analysis. particular, effects ratio ring diameter, ov...

In this paper we consider deflations (inverse pocket flips) of n-gons for small n. We show that every pentagon can be deflated after finitely many deflations, and that any infinite deflation sequence of a pentagon results from deflating an induced quadrilateral on four of the vertices. We describe a family of hexagons that deflate infinitely for a specific deflation sequence, yet induce no infi...

ABSTRACT This study aimed to evaluate three methodologies for orifice-plate water-flow estimation by quantifying errors in the flow determinations propose an appropriate measurement range each evaluated condition. Two models (nominal diameters of 100 and 150 mm) with 50% restriction section were evaluated. In theoretical equations, discharge coefficient was obtained using Reader-Harris/Gallaghe...

We propose a new technique to implement solid wall boundary conditions for steady two-dimensional Euler equations for problems in curved geometries. The technique is to be used with high-order methods on unstructured, straight-sided element meshes. By modeling flow around a physical rather than computational geometry, significant improvement in quality of the solution is achieved. The technique...

Especially, the investigation of the presented systems with respect to their magnetic properties is r...

In this study, a cooling system for fusion reactor divertor that utilizes swirling flow generated downstream of multi-elbow piping was proposed, and fields the (triple elbow) were investigated using visualization experiment. Additionally, heat transfer experiment conducted under one-sided heating condition to simulate environment. The results revealed flux removed by in elbow exceeded critical ...

It is shown that an interferometer using one scatter plate and a plane mirror is well suited for testing long focus optical systems. Stability is automatically achieved in this system because of its +1 magnification. Two methods of introducing straight fringes into the field in order to examine a nearly perfect optical system, and a method of making scatter plates to give high-contrast fringe p...
