Mechanical Properties, Workability, and Experiments of Reinforced Composite Beams with Alternative Binder and Aggregate
<p><span>Arguably the most important element in the sustainability of concrete development is the discovery of an optimal sustainable binder and substitution for the increasingly depleted reserves of natural aggregates. Considerable interest has been shown in alkali-activated materials, which possess good characteristics and could be considered environmentally friendly because of their use of secondary materials in production. The aim of this study was the determination of the mechanical properties of three different mixtures based on the same locally accessible raw materials. The reference mixture contained Portland cement, the second mix contained a finely ground granulated blast furnace slag instead of cement, and the third mixture contained a portion of light artificial aggregate. The experiments focused on the testing and mutual comparison of the processability of the fresh mixture and mechanical characteristics (like compressive and flexural strength, as well as resistance to high temperatures and surface layer tear strength tests). Reinforced concrete beams without shear reinforcement and with three levels of reinforcement were also tested with a three-point bend test. The results show that, overall, the mechanical properties of all the tested mixtures were similar, but each had its own disadvantages. For example, the blast furnace slag-based mixture had a more vulnerable surface layer or a debatable loss of bulk density in the light aggregate mix at the expense of the mechanical properties. One of the main results of the research is that it was possible to technologically produce beams from the alkali-activated concrete (AAC) mixture. Then, the performed beam experiments verified the mechanism of damage, collapse, and load capacity. The obtained results are essential because they present the use of AAC not only in laboratory conditions but also for building elements. In beams without shear reinforcement, the typical tensile cracks caused by bending and shear cracks appeared under loading, where their character was affected depending on the degree of beam reinforcement and loading.</span></p>

Relating hydro-mechanical and elastodynamic properties of dynamically-stressed tensile-fractured rock in relation to fracture aperture and contact area
<p>We exploit nonlinear elastodynamic properties of fractured rock to probe the micro-scale mechanics of fractures and understand the relation between fluid transport and fracture aperture and area, stiffness proxy, under dynamic stressing. Experiments are conducted on rough, tensile-fractured Westerly granite specimen subject to triaxial stresses. Fracture permeability is measured from steady-state fluid flow with deionized water. Pore pressure oscillations are applied at amplitudes ranging from 0.2 to 1~MPa at 1~Hz frequency. During dynamic stressing we transmit acoustic signals through the fracture using an array of piezoelectric transducers (PZTs) to monitor the evolution of fracture interface properties. We examine the influence of fracture aperture and contact area by conducting measurements at effective normal stresses of 10, 12.5, 15, 17.5, and 20~MPa. Additionally, the evolution of contact area with stress is characterized using pressure sensitive film. These experiments are conducted separately with the same fracture and they map contact area at stresses from 9 to 21~MPa. The resulting `true' area of contact measurements made for the entire fracture surface and within the calculated PZT sensor footprints, numerical modeling of Fresnel zone. We compare the elastodynamic response of the the fracture using the stress-induced changes ultrasonic wave velocities for a range of transmitter-receiver pairs to image spatial variations in contact properties, which is informed by fracture contact area measurements. These measurements of the nonlinear elasticity are related to the fluid-flow, permeability, in response to dynamic stressing and similar comparisons are made for the slow-dynamics, recovery, of the fracture interface following the stress perturbations.</p>

Dataset: Scatter of mechanical properties of 2D biaxial and triaxial braided reinforced composites and their correlation with visual features
<p>The data represents tensile tests of 2D braided biaxial and triaxial composite laminates. Braids were produced on a Herzog radial braiding machine RF 1-176-100 with carbon fiber yarns (Toho Tenax F13 HTS40 12K 800 tex). Test laminates are infused with a VARI process with the 2-component epoxy resin system Hexion RIM235/RIMH237. The infusion is performed at vacuum pressure leves of 20-30 mbar and the resin is cured at room temperature for 24 hours at a pressure level of 250 mbar. A subsequent post-cure step maximizes matrix properties at 70°C for 10 hours.<br> The braid setups have been chosen to achieve four different braids with a fiber angle of 45° on braid mandrels with a diameter of 120 mm, two biaxial ones and two triaxial ones. By using different sizes of braiding ring diameters and yarn forces, homogeneous and inhomogeneous fiber architectures are generated.<br> Braiding setups 1 (biaxial) and 2 (triaxial) with 130 mm braiding ring diameter and 350 g yarn force result in braids with homogeneous fiber architecture. 3 (biaxial, 400 mm braiding ring, 600 g yarn force) and 4 (triaxial, 250 mm braiding ring, 600 g yarn force) in braids with inhomogeneous scattering of visual characteristics. Single layers are braided on mandrels with a length of 1500 mm and laminates with 6 layers of biaxial and 4 layers of triaxial braids are subsequently infused.<br> Tensile tests are performed on a Schenck-Trebel RM250 universal testing machine according to AITM 1-0007. For each specimen, the individual fiber orientation in each layer is measured prior to infusion by image analysis performed on scans of the braided layers. The results show a strong dependence of the individual fiber orientation of single test specimens on their mechanical properties in case of the presented tensile tests</p>

First-principles insights into the electronic, optical, thermophysical, and mechanical properties of lead-free cubic novel Ba3SbBr3 perovskite
<p>Lead-free halide perovskites have emerged as a significant class of materials with immense<br> potential for solar cell synthesis. Among these materials, Ba3SbBr3, a halide novel perovskite,<br> exhibits remarkable efficiency and holds promise for solar cell applications. There are a lot of<br> physical properties, including its elasticity, electrical composition, bonding, thermophysical,<br> optoelectronic properties, and optical properties, that remain unexplored. In this study, we<br> employ advanced density functional theory-based computations to investigate and unveil the<br> previously unidentified physical properties of novel Ba3SbBr3. Our research encompasses a wide<br> range of analyses, covering mechanical stability, phonon dispersion properties, thermophysical<br> properties, elastic parameters, and bonding nature. By precisely analyzing the phonon dispersion<br> properties and applying the Born-Huang criteria, we demonstrated it as mechanically stable.<br> Moreover, our investigation demonstrates that Ba3SbBr3 exhibits favorable machinability and</p> <p>mechanical isotropy through the analysis of various elastic parameters. ELATE’s three-<br> dimensional visualization and optical properties also show isotropic behavior in all directions.</p> <p>The electron charge density reveals the possession of the ionic bonding. Additionally, Ba3SbBr3<br> possesses a direct bandgap, which is essential for efficient optoelectronic performance. The study<br> also encompasses an exploration of the thermophysical properties including the melting<br> temperature, Debye temperature, Grüneisen parameter, and thermal expansion coefficient. The<br> higher values observed in these properties highlight the material's enhanced mechanical stability,<br> thermal stability, and overall suitability for optoelectronic device applications. A large range of<br> photoconductivity and absorption coefficient indicates the suitability of its application in solar<br> cells. The comprehensive investigation conducted in this study contributes novel insights into the<br> unexplored physical properties of Ba3SbBr3, providing a solid foundation for future research<br> endeavors. The findings presented here serve as a valuable reference and inspiration for further<br> theoretical and experimental studies in this rapidly evolving field. The knowledge gained from<br> this research holds great promise for advancing the development of solar engineering and device<br> technologies.</p>

Effects of gravel size and content on the mechanical properties of conglomerate
<p>Stress-strain curves and fracture distribution characteristics indicate that gravel content influences the mechanical properties of rocks. In this study, uniaxial compression tests were conducted on the conglomerate containing gravels having diameters between 2–26 mm. In these tests, we found that many micro fractures were generated around evenly distributed gravels. Additionally, we found that as the gravel content increased, the uniaxial compressive strength and elastic modulus of conglomerate decreased; however, the plasticity characteristics of conglomerate increased. The results of our analysis imply that when the gravel content is less than <span><span></span></span> (14.61–31.72 %), the macro mechanical properties are mainly influenced by the cementing material, and between <span><span></span></span> and <span><span></span></span> (78.50 %), failure is determined by the local Orowan additional stress, which is related to the mechanical properties of the cement and the cementing strength,and higher than <i>f</i><sub><i>ch</i></sub><span><span></span></span>, failure is determined by the mutual Hertz stress among the gravels.</p>

Microstructure and mechanical properties of mechanically-alloyed CoCrFeNi high-entropy alloys using low ball-to-powder ratio
<p>The main issue of this work was to analyse the microstructural evolution and mechanical properties of FCC high entropy alloy (HEA) when BPR (ball-to-powder ratio) was limited to 5:1. The motivation of our work is to increase the amount of milled fraction without losing efficiency of the milling process. Nowadays many papers describe HEAs by using powder metallurgy processes, but higher BPR is used. In consequence less amount of powder is milled in one period and the process is not effective enough from the industrial point of view.</p> <p>In this work four equiatomic CoCrFeNi samples were made by Mechanical Alloying plus Spark Plasma Sintering using different milling times: 10, 20, 30, 40 hours. We used 200 Φ5 mm WC balls and milled with intervals 15:15 minutes. Milling speed was 250 rpm. After the mechanical alloying has been finished samples were sintered by using Spark Plasma Sintering technique. We chose 950 °C as a process temperature with heating rate 100 °C/min. Sintering pressure was 50 MPa. Samples were then homogenise in 1050 °C for 12 hours. Then samples were water quenched.</p> <p>The densification of samples during sintering was in satisfied level, what was confirmed by relative densities of samples (>90 %) The microstructure observation of sintered samples revealed Cr-rich particles evenly distributed in samples volume. The number of particles decreases with increasing the milling time. Elements are randomly distributed in the matrix phase except a small Cr-depletion. XRD technique shows multiple FCC structure. As the milling time exceeds, the main FCC structure is promoted. Microhardness increased as a function of milling time. After annealing microstructures were almost out of Cr-rich phase. Only the biggest particles remained. EBSD revealed the grain size decrement as a function of milling time. Also X-ray diffractograms presented significant homogenisation of manufactured samples. Despite the microhardness decrease after heat treatment, the longest milled sample still possess very promising properties. Moreover hardness of samples is not indent’s size dependent (micro- and nanohardness).</p> <p>During milling time the particles are joining and fracturing many times. As a consequence elements are mixing and promoting the new phase(s) growing. We deduced that Hall-Petch effect is the most important factor determining better mechanical properties in longer milled samples. However the milling process need to be improvement. Cr-rich phase observed in sintered samples is the effect of low efficiency of the process, which might be improved by either smaller fraction of Cr at the beginning (premilling process) or increase the other process parameters (milling speed, sintering time).</p>
