Abstract Hydrocolloids are widely used in meat products and pureed foods as they offer thickening and viscosity-enhancing effects that facilitate shaping and improve stability. In this study, the static shear rheological and dynamic viscoelastic properties of pumpkin puree (S) and pork mince (P) with the addition of various hydrocolloids were considered. Dedicated material printing experiments were conducted by means of a three-dimensional printing platform by using a coaxial dual-nozzle for sandwich composite printing of four different materials. In particular, the impact of different process parameters (printing speed 10~30 mm/s, filling density 10%~50%) was assessed in terms… More >

Abstract Squat reinforced concrete (RC) shear walls are essential structural elements in low-rise buildings, valued for their high strength and stiffness. However, research on their seismic behavior remains limited, as most studies focus on tall, slender walls, which exhibit distinct failure mechanisms and deformation characteristics. This study addresses this gap by conducting an extensive review of existing research on the seismic performance of squat RC shear walls. Experimental studies, analytical models, and numerical simulations are examined to provide insights into key factors affecting wall behavior during seismic events, including material properties, wall geometry, reinforcement detailing, and More >

Abstract The main raw material utilized in wood adhesives comes from petrochemical extractives. However, due to the excessive dependence on petrochemical resources and the adverse impact on the ecosystem and human well-being, there is an increasing trend to develop byproduct protein-based adhesives in the current global food safety context. In this research, flaxseed meal was subjected to pretreatment, and trimethylolpropane triglycidyl ether (TTE) and ethylenediamine (EN) were utilized as crosslinkers to establish a more compact adhesive layer and to prevent water intrusion. The pretreatment decreased the FM/UB viscosity by 60% compared to FM. The combination… More > Graphic Abstract

Abstract Intense wind shear (I-WS) near airport runways presents a critical challenge to aviation safety, necessitating accurate and timely classification to mitigate risks during takeoff and landing. This study proposes the application of advanced Residual Network (ResNet) architectures including ResNet34 and ResNet50 for classifying I-WS and Non-Intense Wind Shear (NI-WS) events using Doppler Light Detection and Ranging (LiDAR) data from Hong Kong International Airport (HKIA). Unlike conventional models such as feedforward neural networks (FNNs), convolutional neural networks (CNNs), and recurrent neural networks (RNNs), ResNet provides a distinct advantage in addressing key challenges such as capturing intricate… More >

Abstract Determination of Shear Bond strength (SBS) at interlayer of double-layer asphalt concrete is crucial in flexible pavement structures. The study used three Machine Learning (ML) models, including K-Nearest Neighbors (KNN), Extra Trees (ET), and Light Gradient Boosting Machine (LGBM), to predict SBS based on easily determinable input parameters. Also, the Grid Search technique was employed for hyper-parameter tuning of the ML models, and cross-validation and learning curve analysis were used for training the models. The models were built on a database of 240 experimental results and three input variables: temperature, normal pressure, and tack coat… More >

Abstract The concrete panel of earth-rock dams in cold regions tends to crack due to the combination effect of non-uniform foundation settlement, ice expansion loads, and freeze-thaw damage. In this work, simulations are designed to investigate the effects of freeze-thaw damage degrees on the fracture behavior caused by the partial detachment and ice expansion loads on concrete panels. Results show that the range of detached panels and freeze-thaw damage degree are the dominant factors that affect the overall load-bearing capacity of the panel and the failure cracking modes, whereas the panel slope is a secondary factor.

Abstract Revealing the origin of the mechanical properties of metallic glasses (MG) is a long-standing problem. MGs respond to the external strain with the activation of collective atomic motion, but the triggers of such motions are not revealed yet, in contrast to the well-defined dislocations in crystals. In the present study we show that the change of atomic Von Mises stress is one of the key local parameters to indicate the stress response to a shear strain in metallic glass. Four random Cu50%Zr50% structures were prepared in first-principles molecular dynamics cooling process. Structures were then put… More >

Abstract Shear deformation mechanisms of diamond-like carbon (DLC) are commonly unclear since its thickness of several micrometers limits the detailed analysis of its microstructural evolution and mechanical performance, which further influences the improvement of the friction and wear performance of DLC. This study aims to investigate this issue utilizing molecular dynamics simulation and machine learning (ML) techniques. It is indicated that the changes in the mechanical properties of DLC are mainly due to the expansion and reduction of sp³ networks, causing the stick-slip patterns in shear force. In addition, cluster analysis showed that the sp²-sp³ transitions arise… More >

Abstract Due to excellent physical performance and potential application in the nanoscale fluid channel, 2D transition-metal dioxides and dichalcogenides with 1H phase are of great interest. Their mechanical property attracts much attention but the accurate evaluation still faces challenges because of the ultrasoft and ultrathin structure. In this work, we establish an analytical atom-based molecular mechanics model to predict the elastic modulus, Poisson’s ratio and shear modulus of the single-layer 2D transition-metal dioxides and dichalcogenides. The proposed method is validated through the calculation of the mechanical property of Molybdenum disulfide (MoS₂). The results indicate that the elastic… More >

Abstract Scouring experiments were conducted using a three-dimensional laser scanning technology for angles of the jet spanning the interval from 0° to 30°, and the characteristics of the scour hole in equilibrium conditions were investigated accordingly. The results indicate that the optimal scouring effects occur when the jet angle is in the ranges between 15° and 20°. Moreover, the dimensionless profiles of the scour hole exhibit a high degree of similarity at different jet angles. Numerical simulations conducted using the Flow-3D software to investigate the bed shear stress along the jet impingement surface have shown that More >
