Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Pure bending of beams made of multimodular behavior material under creep conditions

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
The problem of pure bending of beams with rectangular and circular cross-section is solved at steady-state creep, taking into account the different characteristics of the material in tension and compression.

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 ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

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.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Vibration and buckling of cross-ply composite beams using refined shear deformation theory

open access: yes, 2012
Vibration and buckling analysis of cross-ply composite beams using refined shear deformation theory is presented. The theory accounts for the parabolical variation of shear strains through the depth of beam.

Shear resistance of reinforced concrete beams with and without steel fibres. [PDF]

open access: yes, 1981
The fabrication and placement of conventional shear rein- forcement are time consuming and costly and its use in thin structural concrete members is often impractical.

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.
