This numerical study is done to evaluate the effect of confinement on axial capacity and ductility thin section columns using plastic damage plasticity (CDP) model in Abaqus. Seven specimens short with size 100x400x300 mm subjected uniaxial compression loads were analyzed based material parameters modeling technics that first validated an experimental specimen. The variation was made by changes...

Accelerometers for movement registration have the potential to reflect the volume, pattern, intensity, type, and energy expenditure of physical activity(1,2). Developments are still ongoing with regard to reduction of the size of the instruments, lengthening of battery life and translation of the output to meaningful information for the user. Instruments with the capacity for most or all functi...

A&me-The axial dispersion problem formulated in part I[11 of this series is solved for cases 2-4 and 7 identified therein. The cases analyzed here consider appendages to the finite axially dispersed reactor which are either semi-infinite sections of finite dispersion or well-mixed sections of tinite capacity. The findings possess features akin to those found in Part II[q for case 1 but obviousl...

understanding how a cutout influences the load bearing capacity and buckling behavior of cylindrical shells is fundamental in the design of structural components used in automobiles, aircrafts, and marine structures. in this article, simulation and analysis of steel cylindrical shells with various lengths, include quasi elliptical cutout, subjected to axial compression were systematically carri...

The principle of Angular Multiplexing to realise independent communication channels in a relatively short step-index plastic optical fibre is described. This concept of Mode Group Diversity Multiplexing is based on the principle that the axial angle of light propagating in a step index multimode fibre is preserved over relative short distances. By using an array of lasers each launching light i...

To investigate the axial compressive behavior of an opening cold-formed thin-wall C-steel combined double-limb column, I-section columns were modeled in this paper, and models validated by experiments on axial-compressed columns. Parametric analyses carried out The effects slenderness ratio, height to thickness width bolt spacing, web ultimate bearing capacity investigated. It was observed that...

Recent changes in telecommunication regulations and changing market forces are making the market for broadband network services to the home an extremely lucrative and competitive area. Of the many competing technologies for such broadband services, major CATV companies are banking heavily on Hybrid Fiber Co-axial (HFC) networks as a delivery mechanism. In this paper we provide a mathematical mo...
