Dynamic Behavior of Shafts, Couplings and Working Body of the Machine under Torsional Impact Moment [PDF]

open access: yes
In this study, the influence of the torsional rigidity of the connected shafts, couplings and the working body of the machine, as well as the damping capacity of the coupling, on the torsional impact moment generated in the machine transmission is ...

Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

open access: yesSmall, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality

open access: yesSmall, EarlyView.
2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.

Flexural-Torsional Buckling Analysis of Steel Beam with Reduced Flanges

open access: yes, 2011
Flexural-torsional buckling of the beam in steel frame with reduced beam section (RBS) connections is analyzed. Base on the analysis of flexural-torsional buckling of the RBS beam under different loads using energy method, the critical moment calculation

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

open access: yessteel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Behaviour and Strength of Steel Twin Girder Systems with Torsional Braces

open access: yes, 2014
This study is motivated to investigate the behaviour and strength of beams with only discrete torsional bracing. The experimental program of a scaled twin-girder system with different arrangements of lateral and torsional bracing was conducted ...

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

open access: yesStructural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...
