A refined finite element analysis on the thermal conductivity of perforated hollow sphere structures
Computational Materials Science, 2009Abstract This work addresses the thermal properties of perforated hollow sphere structures. Hollow sphere structures are a new material with significant areas of application in thermal insulation, structural and acoustic damping and controlled deformation at low stress levels.

A hollow-core terahertz fiber composed of Bragg anti-resonant elements in a hexagonal structure is proposed. The function of Bragg elements on the transmission losses and bending losses of the hollow-core terahertz fiber is investigated using finite element method.

Finite element analysis of hollow structural sections subject to torsion and combined loading
2021The reliability of steel structures is governed by design codes which may vary between countries. These codes may stipulate factors of safety, quality, and loading conditions. The approved steel design codes ensure each structure is designed with the same quality, recommended loading conditions, and safety standards for the design life of the structure.

Elastic finite element analysis on cross‐sections of random hollow sphere structures
Materialwissenschaft und Werkstofftechnik, 2010AbstractThis paper addresses elastic analysis based on 2D finite element models for metallic hollow‐sphere structures. In the first part, the influence of micro‐porosity on the elastic behaviour of sintered metallic hollow sphere wall material is investigated.

Hollow fibers containing various display elements: A novel structure for electronic paper
Journal of the Society for Information Display, 2006Abstract— A novel structure for electronic‐paper displays using hollow fibers has been developed, where the hollow fiber is comprised of an outer transparent polymer tube and inner display elements (rotating balls, electrophoretic dispersion fluid, or cholesteric liquid crystals).

Design and application of superelements in efficient prediction of the structural behavior in a short time has been one of the research interests in the last decade. Superelements are those elements which are capable of producing the same accurate result instead of several combined simple elements.

AbstractThis work investigated the thermal properties of a new type of hollow sphere structures. For this new type, the sphere shell is perforated by several holes in order to open the inner sphere volume for a matrix material. The effective thermal conductivity of syntactic (i. e.

Abstract Although branch plate-to-circular hollow section (CHS) connections under branch axial load are simple to fabricate and cost-effective, they generally experience significant deformation at relatively low loads resulting in an imposed deformation limit.

Abstract Analytical formulae based on yield line theory need to be validated by a rational determination of the yield load from experimental results. Such a comparison is then complicated by the inability to conclusively determine the yield load from load-deformation curves. Existing methods for determining the yield load from load-deformation curves
