Comparative Analysis of Steel Reinforced and Bamboo Reinforced Beams

open access: yesRekayasa Sipil, 2019
This research will seek to compare bamboo reinforced concrete beams and steel reinforced concrete beams experimentally. Special emphasis will be laid on how both sets of beams respond to nominal moments.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Theoretical and numerical analysis of reinforced concrete beams with confinement reinforcement

open access: yesRevista IBRACON de Estruturas e Materiais
This paper discusses the use of confinement in over-reinforced concrete beams. This reinforcement consists of square stirrups, placed in the compression zone of the beam cross-section, in order to improve its ductility.

Beam-beam

open access: yes
The interaction of the two beams in a collider leads to a variety of effects that may limit the performance of the machine. This lecture introduces the basic aspects necessary to understand the design of modern colliders.

Beam-Beam Interactions [PDF]

open access: yes, 2003
At the interaction point of a particle accelerator, various phenomena occur which are known as beam-beam effects. Incident bunches of electrons (or positrons) experience strong electromagnetic fields from the opposing bunches, which leads to electron deflection, beamstrahlung and the creation of electron/positron pairs and hadrons due to two-photon ...

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Behaviour under cyclic loading of strengthened beams

open access: yesRevista IBRACON de Estruturas e Materiais, 2017
This work presents a study on the behavior of reinforced concrete beams strengthened in bending by the addition of concrete and steel on their tension side and having expansion bolts as shear connectors at the junction between the beam and the jacket ...

Beam-beam instability [PDF]

open access: yes, 1983
The subject of beam-beam instability has been studied since the invention of the colliding beam storage rings. Today, with several colliding beam storage rings in operation, it is not yet fully understood and remains an outstanding problem for the storage ring designers.

Revisit of combined parallel‐beam/cone‐beam or fan‐beam/cone‐beam imaging [PDF]

open access: yesMedical Physics, 2013
Purpose:This aim of this paper is to revisit the parallel‐beam/cone‐beam or fan‐beam/cone‐beam imaging configuration, and to investigate whether this configuration has any advantages.Methods:Twenty years ago, it was suggested to simultaneously use a parallel‐beam (or a fan‐beam) collimator and a cone‐beam collimator to acquire single photon emission ...

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

open access: yesAdvanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.
