In this study, the researchers investigated the compressive failure mechanisms in flax fiber composites, a promising eco-friendly alternative to synthetic composite materials, through both numerical simulations and experimental analysis. They examined the reasons behind the low compressive strength in comparison to tensile strength, focusing on the compressive-to-tensile strength ratio. A novel thermodynamically consistent continuum damage micromechanics model was introduced to capture the ev... Read more

X-ray computed tomography (XCT) has been shown to reveal the true extent of ductile damage below the fracture surface of failed test specimens, which is often significantly underestimated when probed using 2D serial sectioning techniques and a microscope, since a single plane of material may only exhibit only a handful of resolvable voids.

In contrast XCT offers the capability to generate large datasets consisting of hundreds, if not thousands, of individually resolvable voids, where e... Read more

The interest in potential applications produced with self-compacting fibre reinforced concrete continues to grow, but in practice, problems associated with an uneven distribution and orientation of fibres in the concrete structure occur. It is not clear what exactly influences uneven distribution of fibres in selfcompacting concrete (SCC) mixtures, especially during the casting and how different factors influence fibre orientation. The objective of this work was to investigate how rheological... Read more

To accurately predict the initiation and evolution of uranium hydride potentially present in nuclear waste containers, studies of simulated conditions are required.

Here, for the first time, the uranium-deuterium reaction was examined in-situ, in real time, whilst within grouted media. A deuterium gas control rig and stainless steelquartz glass reaction cell were configured on a synchrotron beam line to collect X-ray diffraction and X-ray tomography data. It was found that deuteride fo... Read more

The cleanliness of liquid steel is defined by the amounts of dissolved unwanted impurities and precipitated unwanted non-metallic phases.[…] Improving the cleanliness of the steel would mean a lower fraction of impurities in the final product. […] A novel approach, utilizing controlled synthetic inclusion/metal samples, has been developed to study the reactions between free inclusion-slag droplets and steel. The technique combines High-Temperature Confocal Scanning Laser Microscop... Read more

The non-metallic inclusions are mostly harmful to the propertiesof the steel products. The effective characterization of the size, morphology, and distribution of the inclusions in steel is a key issue to remove and control the inclusions in the Read more

X-ray Computed Tomography (X-ray CT) has become a vital tool for product quality inspection. The X-ray CT analysis of 3D printed composites, with a layer-by-layer structure of carbon fibre/polyamide and polyamide plies, demonstrates how the void content increases with an increasing number of consecutive carbon fibre layers. Not only the void content, but also the pore
network complexity increases, as more pore types are introduced into the sample. The PolyAmide (PA) matrix has an averag... Read more

In this paper a study concerning an automatic determination of distribution of steel fibres in self-compacting concrete (SCC) is presented. The determination of fibre distribution is required to assess any relationship between those features and casting methods of concrete elements. Concrete beams with steel fibres of various types and casting methods were examined. Involved methods were computed tomography imaging followed by image analysis. After image analysis a label map consisting of all... Read more

Laser-matter interactions in laser additive manufacturing (LAM) occur on short time scales (10^-6 – 10^-3 s) and have traditionally proven difficult to characterise. We investigate these interactions during LAM of stainless steel (SS316 L) and 13-93 bioactive glass powders using a custom built LAM process replicator (LAMPR) with in situ and operando synchrotron X-ray radiography. This reveals a range of melt track solidification phenomena as... Read more

The use of novel multi-scale correlative methods, which involve the coordinated characterization of matter across a range of length scales, are becoming of increasing value to materials scientists. Here, we describe for the first time how a multi-scale correlative approach can be used to investigate the nature of ductile fracture in metals. Specimens of a nuclear pressure vessel steel, SA508 Grade 3, are examined following ductile fracture using medium and high-resolution 3D X-ray computed to... Read more
