Enhancing printability of 3D printed concrete by using metakaolin and silica fume
Structural Concrete, EarlyView.Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.

Structural Concrete, EarlyView.Abstract The accurate prediction of the shear capacity of reinforced concrete underpins the efficient and safe design of concrete buildings and infrastructure. Disagreement remains about shear mechanisms and the modeling of shear resistance. For slender beams without shear reinforcement, critical shear crack (CSC) models have attracted interest.

Failure Probability Evaluation of GIL Tri‐Post Insulators Under Electromechanical Stresses
High Voltage, EarlyView.ABSTRACT Based on the energy theory, this paper proposes an evaluation method for the breakdown failure probability of the tri‐post insulator in a gas‐insulated metal‐enclosed transmission line (GIL). Various internal defects, vector forces and torque forces were considered, along with the application of an AC voltage.

European Journal of Oral Sciences, EarlyView.Abstract Epoxy resin‐based sealers are commonly used in endodontic treatment due to their superior physicochemical properties. Therefore, it is important to utilize these materials by enhancing their properties. Nonetheless, several of their properties remain suboptimal, including the relatively prolonged setting time, the moderate yet clinically ...

Journal of Prosthodontics, EarlyView.Abstract Purpose This study aims to evaluate the effects of adding titanium dioxide (TiO2) nanotubes (NTs) to three‐dimensional (3D) printed denture base resin on the thermal and thermomechanical properties, which have high clinical relevance. Materials and Methods TiO2 NTs with dimensions of 30–70 nm in diameter and 2–4 µm in length were added to the ...

Micromechanical model of crack growth in fiber reinforced ceramics [PDF]
A model based on the micromechanical mechanism of crack growth resistance in fiber reinforced ceramics is presented. The formulation of the model is based on a small scale geometry of a macrocrack with a bridging zone, the process zone, which governs the

JOR SPINE, Volume 9, Issue 1, March 2026.Using advanced multiaxial bioreactor systems, this study investigated the effects of flexion, torsion, and static compression on whole intervertebral discs. High cycle asymmetric loading resulted in cell death in the nucleus pulposus and structural changes in the annulus fibrosus.

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 933-962, March 2026.ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that
