With the aim of investigating factors influencing hysteretic behavior common steel bars with unbonded sections (CS-US), hysteresis tests six CS-US specimens were conducted, taking length, location section, bar diameter, strength grade, and concrete grade as study variables. The results show that there exist necking phenomena in different degrees damage to all specimens. A 3D fine model was established by Solid works ABAQUS software verified according experimental results. simulated values...
Citric acid-treated zeolite Y (CY) and beta were mechanically mixed to obtain composite zeolites (CY-Beta) with various contents. The used as the acid components of hydrocracking catalyst supports. physical chemical properties supports catalysts analyzed by N2 adsorption-desorption, XRD, SEM, NH3-TPD. mechanical mixing CY does not destroy textual original zeolites. However, acidity fit linearly calculated value two because some sites are covered or reacted other during process. In addition,...
The authors simulate in three dimensions the molecular beam epitaxial growth of InxGa1−xN with classical dynamics. Atomic interactions are simulated Stillinger–Weber potentials. Both homoepitaxial and heteroepitaxial growths studied. effects substrate temperature indium concentration on quantum dot morphology, profiles, thickness wetting layers qualitatively agree experimental findings. authors’ simulations support earlier suggestions that formation InGaN/GaN system is governed by a...
With the continuous utilization of renewable energy, number onshore wind turbines is increasing. Small design improvements can save costs and facilitate maintenance repair turbine foundation. In this paper, an existing gravity expansion foundation with anchor cage improved. Our further expand space inside reduce length bolt, which could construction. To study performance new foundation, a three-dimensional finite element model foundation–soil–anchor bolt was established via simulation. The...

The detection of bolt looseness is crucial to ensure the integrity and safety bolted connection structures. Percussion-based provides a simple cost-effective approach. However, this method has some inherent shortcomings that limit its application. For example, it highly depends on inspector's hearing experience more easily affected by ambient noise. In article, whole set signal processing procedures are proposed new kind damage index vector constructed strengthen reliability robustness...
The fatigue crack growth properties of G20Mn5QT cast steel and corresponding butt welds, using compact tension specimens, were monitored investigated via acoustic emission (AE) techniques. Fatigue is a combination cyclic plastic deformations before the tip, tensile fractures, shear fractures. release maximum amount energy, which accounts for half total second-largest number AE signals, are continuous-wave type. fractures energy largest burst-wave least lowest similar to burst type, albeit...
Abstract The floating raft vibration isolation system includes upper and lower isolators middle raft. As one of the most important parts that affect performance isolation, is usually assumed to be an undamped or viscous damping structure in analysis, which different from actual situation. To study effects with hysteresis characteristics, a three-freedom complex stiffness mechanical model was built, approach for calculating raft's force transmission rate derived impedance methods. Based on...
Lithium plating is a known issue of rechargeable lithium-ion cells with carbon-based anodes. Accumulated metallic lithium growth accelerates aging and internal short circuit failures. Preventing an important consideration for cell design operations. In real world applications, the in battery pack will age very likely they differently sometimes are used extreme conditions then it raises questions how to detect control service. A variety factors influence including variables, intrinsic...

NaP zeolite was synthesized via ultrasonic-assisted hydrothermal synthesis. The methods for Cu or Fe doping were screened. Oxidation process of methylene blue (MB) and methyl violet-6B (MV-6B) by doped zeolites surveyed. NaPultra exhibited higher crystallinity (94.99%), while crystallization temperature time decreased from 120oC to 90oC 8 h 4 than At an ultrasonic power intensity 30% density 60 mL/W, the conversion rate Si Al increased 66.46% 84.68% 73.75% 95.25%.

Abstract A floating raft is a complicated multilayer vibration isolation system, which often simplified as two-degree-of-freedom viscous damping system in analysis. In order to research the influences of hysteretic and flexibility on effect, three-degree freedom mechanical model established, impedance method adopted deduce force transmissibility raft. The analytic calculation methods are given aiming at low-frequency range, resonance high-frequency respectively. Finally, influence rules...
