Effects of stiffener area in composite steel-concrete beam with web opening: numerical, experimental and theoretical investigation

open access: yesFrontiers in Materials
Generally, the Openings in composite steel-concrete beams (CBs) for conduits and pipelines often compromise their flexural capacity. To mitigate this, longitudinal stiffeners (LS) and transverse stiffeners (TS) are strategically placed near the web ...

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Investigations and Improvement of the Joint Between Narrow Steel Beams and CFST Columns

open access: yesBuildings
In this paper, the forked-web joint configuration was introduced first, in order to transfer the shear and moment forces better and avoid the local buckling problem that usually happens in narrow steel beams and concrete-filled steel tubular (CFST ...

Reinforcing the Octagonal Web Openings of Castellated Beam by Steel Rings

open access: yesAl-Qadisiyah Journal for Engineering Science, 2019
Castellated steel beams are section steel members with hexagonal or octagonal web openings which they are made from standard hot rolled steel section I or H. The main advantage of these members is their economic material.

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

open access: yesPolymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...

Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
This review systematically summarizes a full spectrum of non‐invasive diagnostic approaches for portal hypertension (PH), including imaging modalities, elastography, serum biomarkers, composite scoring systems and endoscopic ultrasound‐guided portal pressure gradient (EUS‐PPG), and analyzes their performance across different liver disease etiologies ...

Deformation, Creep, and Dynamics in Glassy Ionomers

open access: yesJournal of Polymer Science, EarlyView.
Ionic architecture tunes the inelastic deformation of glassy ionomers. Simulations show that ionic associations leave the small‐strain elastic baseline nearly unchanged, but strongly reinforce yielding, strain hardening, and creep resistance. Polyampholyte architectures suppress nonaffine mobility and stress‐induced fluidization most effectively by ...

Comparative Evaluation of Large Amplitude Oscillatory Shear (LAOS) Analysis Methods for Detecting Surfactant‐Induced Structural Evolution in Xanthan Gum Solutions

open access: yesJournal of Polymer Science, EarlyView.
A comparative large‐amplitude oscillatory shear analysis reveals how cationic surfactants progressively weaken xanthan gum networks. While conventional rheology identifies network softening, advanced LAOS methods uncover nonlinear deformation mechanisms and transient structural evolution that remain hidden in cycle‐averaged measurements.
