Observations of a glaciating hole-punch cloud [PDF]

, 2009
Remote-sensing measurements of a hole-punch cloud or fall-streak hole are presented. The cloud was observed with a vertically pointing infrared ceilometer, Doppler lidar, sky camera and a polarimetric radar inclined at 45 degrees. The Doppler lidar and polarimetric radar observations show that the aircraft-induced fall streak was composed primarily of ...

Self‐Maintainable Electronic Materials with Skin‐Like Characteristics Enabled by Graphene‐PEDOT:PSS Fillers

Advanced Science, EarlyView.
Graphene‐PEDOT:PSS fillers revolutionize soft electronics by transforming jelly‐like materials into skin‐like systems with self‐healing, heat‐responsiveness, and multiplex sensing capabilities. This novel material exhibits exceptional printability, flexibility, and adhesiveness, enabling seamless integration into bioelectronics and tissue‐cyborganic ...

Efficient 3D modelling of punching shear failure at slab-column connections by means of nonlinear joint elements [PDF]

, 2019
Failures of isolated slab-column connections can be classified as either flexural or punching. Flexural failure is typically preceded by large deformation, owing to flexural reinforcement yield, unlike punching failure which occurs suddenly with little ...

Construction of Protein‐Like Helical‐Entangled Structure in Lithium‐Ion Silicon Anode Binders via Helical Recombination and Hofmeister Effect

Advanced Science, EarlyView.
This study presents a gelatin‐xanthan gum composite binder featuring a protein‐like helical‐entangled structure, formed through thermo‐responsive recombination and the Hofmeister effect. This innovative structure, akin to protein behavior, absorbs stress and strain, thereby enhancing the cycling stability and rate performance of silicon anodes in ...

Punching strengthen

Alexandria Engineering Journal, 2015
An experimental and analytical study on the punching strengthening of reinforced concrete two-way slabs using external steel plates is presented. Five reinforced concrete square slabs of 100 mm thickness were tested over simply supported four sides of ...

Critique of Critical Shear Crack Theory (CSCT) for fib Model Code Articles on Shear Strength and Size Effect of RC Beams [PDF]

arXiv, 2018
The size effect of Muttoni et al.'s CSCT is shown to be very close and asymptotically identical to the energetic size effect law (SEL) extensively verified experimentally and theoretically (due to appear in the 2019 ACI Code for both beam shear and punching). However, the CSCT derivation and calculation procedure obfuscates the mechanics of failure. It

Detachment of a rigid flat punch from a viscoelastic material [PDF]

arXiv, 2022
We show that the detachment of a flat punch from a viscoelastic substrate has a relatively simple behavior, framed between the Kendall's elastic solution at the relaxed modulus and at the instantaneous modulus, and the cohesive strength limit. We find hardly any dependence of the pull-off force on the details of the loading process, including maximum ...

Ultrasound Cavitation Enables Rapid, Initiator‐Free Fabrication of Tough Anti‐Freezing Hydrogels

Advanced Science, EarlyView.
This work establishes a foundation for high‐performance sonogel fabrication using non‐focused and focused ultrasound, and demonstrates that ultrasound cavitation enables rapid, initiator‐free, and oxygen‐tolerant formation of hydrogels with superior mechanical and physical properties. .

Efficient strategy for modelling punching failure of flat slabs [PDF]

, 2019
This thesis develops a novel modelling strategy depicted JSPM (joint-shell punching model) for simulating punching failure of reinforced concrete (RC) slabs in which non-linear joint elements are combined with nonlinear 2-D shell elements.
