The Development of Controlled Orientation of Fibres in SFRC [PDF]
Materials, 2021 The article is focused on finding the possibility of the controlled orientation of fibres in fibre reinforced concrete constructions. This is because the controlled orientation of the fibres can contribute to the improvement of some properties of fibre reinforced concrete.

Industrial Crops and Products, 2020 Fibre orientation is an essential factor governing the mechanical properties of composite materials. This study proposes an original method based on gray-level granulometry to analyse the fibre orientation distribution (FOD) of synthetic and natural fibre reinforcements aiming composite applications.

Fibre orientation and distribution in steel fibre reinforced concrete
, 2023 The structural performance of steel fibre reinforced concrete (SFRC) composites, including ultra-high-performance concrete (UHPC), is sensitive to the orientation and distribution of fibres achieved during casting. Fibre distribution resulting from a concrete flow during casting is generally non-uniform, biased, and challenging to determine.

Collagen fibre orientation in human bridging veins [PDF]
Biomechanics and Modeling in Mechanobiology, 2020 Bridging veins (BVs) drain the blood from the cerebral cortex into dural sinuses. BVs have one end attached to the brain and the other to the superior sagittal sinus (SSS), which is attached to the skull. Relative movement between these two structures can cause BV to rupture producing acute subdural haematoma, a head injury with a mortality rate ...

ESTIMATION OF FIBRE ORIENTATION FROM DIGITAL IMAGES
Image Analysis & Stereology, 2011 In this paper, estimation of fibre orientation is studied for fibre systems observable as a blurred greyscale image. The estimation method is based on scaled variograms observed along a set of sampling lines in different directions. The parameters of the orientation distribution are obtained numerically. Simulated data are used to study the statistical

The effect of reorientation of the fibre orientation distribution on fibre tracking
, 2012 Diffusion weighted imaging (DWI) allows to delineate neural fibres, based on local, directional information of the diffusion of water. Due to its directional nature, the local information needs to be reoriented upon image transformation, in order to preserve correspondence to the anatomy.

A gyral coordinate system predictive of fibre orientations [PDF]
NeuroImage, 2018 When axonal fibres approach or leave the cortex, their trajectories tend to closely follow the cortical convolutions. To quantify this tendency, we propose a three-dimensional coordinate system based on the gyral geometry. For every voxel in the brain, we define a "radial" axis orthogonal to nearby surfaces, a "sulcal" axis along the sulcal depth ...

Simulation of inertial fibre orientation in turbulent flow [PDF]
Physics of Fluids, 2016 The spatial and orientational behaviour of fibres within a suspension influences the rheological and mechanical properties of that suspension. An Eulerian-Lagrangian framework to simulate the behaviour of fibres in turbulent flows is presented. The framework is intended for use in simulations of non-spherical particles with high Reynolds numbers ...

Fibre orientation in self-compacting fibre reinforced concrete
, 2008 Self-compacting fibre reinforced concrete (SCFRC) combines the benefits of SCC in the fresh state with an enhanced postcracking performance in the hardened state thanks to the fibres. The main properties of SCFRC in the fresh state will be affected by the fibres. The beneficial effect of the fibres in the hardened state (i.e.
