Abstract This study investigates the thermo–mechanical behavior of C40 concrete and reinforced concrete subjected to elevated temperatures up to 700°C by integrating experimental testing and advanced numerical modeling. A temperature-indexed Concrete Damage Plasticity (CDP) framework incorporating bond–slip effects was developed in Abaqus to capture both global stress–strain responses and localized damage evolution. Uniaxial compression tests on thermally exposed cylinders provided residual strength data and failure observations for model calibration and validation. Results demonstrated a distinct two-stage degradation regime: moderate stiffness and strength reduction up to ~400°C, followed by sharp deterioration beyond 500°C–600°C, with residual capacity at… More >

Abstract Brittle materials fail by means of rapid cracks. At their tips, tensile cracks dissipate elastic energy stored in the surrounding material to create newly fractured surfaces, precisely maintaining 'energy balance' by exactly equating the energy flux with dissipation. Using energy balance, fracture mechanics perfectly describes crack motions; accelerating from nucleation to their maximal speed of cR, the Rayleigh wave speed. A tensile crack speed greater than cR is generally considered impossible [1]. Recently, a new mode of tensile crack propagation faster than cR that is not incorporated in classical fracture mechanics has been predicted in… More >

Abstract The rigidity of the resin matrix is a critical factor affecting the impact resistance of composites [1]. However, the intrinsic relationship between resin matrix rigidity and ballistic performance remains insufficiently understood. To reveal the influence mechanisms of resin matrix rigidity on ballistic performance, this study compares the ballistic limits of PBO-140, PBO-200, Aramid III, and Aramid II fiber reinforced composites with resin matrices of different rigidities (epoxy resin, PX90, and PX30) through ballistic impact tests. The experimental results show that, the ballistic limit of composites with PX90 resin is higher than that of composites with… More >

Abstract Powder based high speed sintering (HSS) improves the printing efficiency compared to SLS printing. The shortened layer time for HSS requires quick melting and solidification of powders, which is a big challenge for traditional printing powders materials, especially the viscous elastomers. Herein, a dynamic cross-linked polyurethane containing Diels-Alder bonds (PUDA) was synthesized at kilo scale and used for HSS. The incorporation of dynamic DA bonds into PU enables the dissociation of the polymer chain under IR light heating, and will lead to fast relaxation, diffusion and dis/re-entanglement, addressing the problem of incomplete sintering and weak… More >

Abstract As prestressed concrete (PC) structures age, long-term effects, e.g., creep, shrinkage, and prestress losses, compromise their structural performance. Strengthening these aged PC beams has become a crucial matter. One effective solution is to use externally bonded fiber-reinforced polymer (FRP) sheets; however, limited research has been done on aged PC beams using the FRP, especially for beams with unbonded prestressing strands (UPC beams). Therefore, this research investigates the flexural strengthening efficacy of external FRP sheets on aged UPC beams with unbonded tendons. Aging minimally affected the failure modes of UPC beams, with nonstrengthened beams showing flexural… More >

Abstract Rubberized concrete is one of the most studied applications of discarded tires and offers a promising approach to developing materials with enhanced properties. The rubberized concrete mixture results in a reduced modulus of elasticity and a reduced compressive and tensile strength compared to traditional concrete. This study employs finite element simulations to investigate the elastic properties of rubberized mortar (RuM), considering the influence of inclusion stiffness and interfacial debonding. Different homogenization schemes, including Voigt, Reuss, and mean-field approaches, are implemented using DIGIMAT and ANSYS. Furthermore, the influence of the interfacial transition zone (ITZ) between mortar… More >

Abstract The increase in wood and wood-based products in the construction and furniture sectors has grown exponentially, generating severe environmental and socioeconomic impacts. Particleboard panels have been the main cost-benefit option on the market due to their lightness and lower cost compared to solid wood. However, the synthetic adhesives used in producing traditional particleboard panels cause serious harm to human health. Developing particleboard panels with fibrous waste and natural adhesives could be a sustainable alternative for these sectors. The work aimed to create particleboards with fibrous wastes from the pseudostem of the banana tree (Musa paradisiaca) and… More > Graphic Abstract

Abstract This study investigates the bond performance at the interfacial region shared by Ultra-High Performance Concrete (UHPC) and steel tubes through push-out tests. This study examines how changes in steel fiber volumetric ratio and thickness of steel tube influence the bond strength characteristics. The results show that as the enhancement of the steel tube wall thickness, the ultimate bond strength at the interface improves significantly, whereas the initial bond strength exhibits only slight variations. The influence of steel fiber volumetric ratio presents a nonlinear trend, with initial bond strength decreasing at low fiber content and increasing 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 3D concrete printing (3DCP) has challenges in weak interlayer bond strength and steel reinforcement integration. Existing methods to improve the interlayer bond strength and integrate steel reinforcement have limitations in automatic operation and limited mechanical performance improvement. Strain hardening cementitious composites (SHCC), with the high tensile strength and tensile strain capacity, have the potential to achieve self-reinforced structures in 3DCP. Nevertheless, the wider adoption of SHCC in 3DCP is limited by the high cost of fibers and fiber agglomeration during printing.
To fill the gap, this study investigates the use of SHCC as bonding agent of… More >
