Abstract This research utilizes analytical solutions to investigate the issue of nonlinear static bending in nanobeams affected by the flexomagnetic effect. The nanobeams are exposed to mechanical loads and put in a temperature environment. The equilibrium equation of the beam is formulated based on the newly developed higher-order shear deformation theory. The flexomagnetic effect is explained by the presence of the strain gradient component, which also takes into consideration the impact of small-size effects. This study has used a flexible transformation to derive the equilibrium equation for a single variable, which significantly simplifies the process of More >

Abstract This paper presents a novel mixed finite element method for the free vibration analysis of composite periodic beams. The governing state-space equations are derived based on the Hamilton's principle, treating both displacements and stresses as fundamental variables. This method uses transfer relations in the transverse direction and finite element discretization in the longitudinal direction of the beam, forming a semi-analytical computational framework. Therefore, it is able to handle general composite beam structures containing both transversely layered and axially jointed materials.
The proposed mixed finite element method ensures continuity of both displacements and stresses across material interfaces,… More >

Abstract This article presents research focused on developing and scientifically substantiating a technology for producing environmentally friendly glued structures from wood treated through a two-stage process. The methodology involves preliminary thermal modification followed by high-frequency low-temperature plasma treatment. Thermal modification enhances performance characteristics such as resistance to rot, lowers hygroscopicity, and increases dimensional stability. However, it can diminish the adhesive properties of wood, complicating the bonding process. To address this challenge, the study introduces high-frequency low-temperature plasma treatment, which activates the wood surface, improving wettability and adhesion while minimizing glue consumption. Experimental results indicate that plasma 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 This investigation examines the shear performance of concrete T-beams reinforced with thin layers of ultra-high performance concrete (UHPC) through an approach that integrates experimental evaluation, numerical simulation, and practical project verification. The research is based on a real bridge, and in accordance with the similarity principle, three reduced-scale T-beams with varying UHPC thicknesses were fabricated and tested to examine their failure modes and shear behaviors. A finite element model was created to enhance understanding of how UHPC reinforces these structures, while also considering the effects of material strength and arrangement. In addition to the laboratory… More >

Abstract This study investigates the flexural performance of ultra-high performance concrete (UHPC) in reinforced concrete T-beams, focusing on the effects of interfacial treatments. Three concrete T-beam specimens were fabricated and tested: a control beam (RC-T), a UHPC-reinforced beam with a chiseled interface (UN-C-50F), and a UHPC-reinforced beam featuring both a chiseled interface and anchored steel rebars (UN-CS-50F). The test results indicated that both chiseling and the incorporation of anchored rebars effectively created a synergistic combination between the concrete T-beam and the UHPC reinforcement layer, with the UN-CS-50F exhibiting the highest flexural resistance. The cracking load and… More >

Abstract Background: Radical prostatectomy has long been the treatment of choice for men with clinically significant prostate cancer (PCa) in those with concurrent significant lower urinary tract symptoms (LUTS). For men who meet this description with marked prostatomegaly, we present a multi-institutional proof of concept study describing an alternative pathway of robotic simple prostatectomy (RASP) followed by external beam radiation therapy (EBRT) for the treatment of clinically significant prostate cancer. Methods: A retrospective study was performed of 17 patients with PCa who underwent RASP followed by EBRT at two institutions from 2015–2023. Demographic, peri-operative, and post-radiation… More >

Abstract Sediment mapping is a crucial component of environmental science, particularly in the marine environment, where the analysis of seabed sediments is essential for various purposes, including marine resource management, habitat preservation, and infrastructure development. Sediment refers to the solid particles that are transported and deposited in different areas. Multibeam echosounders have revolutionized the field of seabed sediment mapping by providing unparalleled resolution and accuracy in seafloor surveys. This study aimed to produce sediment maps by implementing multi-frequency, e.g., 200, 400, 550, and 700 kHz multibeam data using a machine learning algorithm, e.g., Support Vector Machine… More >

Abstract As primary load-bearing components extensively utilized in engineering applications, beam structures necessitate the design of their microstructural configurations to achieve lightweight objectives while satisfying diverse mechanical performance requirements. Combining topology optimization with fully coupled homogenization beam theory, we provide a highly efficient design tool to access desirable periodic microstructures for beams. The present optimization framework comprehensively takes into account for key deformation modes, including tension, bending, torsion, and shear deformation, all within a unified formulation. Several numerical results prove that our method can be used to handle kinds of microstructure design for beam-like structures, e.g., More >
