Flexural and shear strengthening of RC beams with composites materials: the influence of cutting steel stirrups to install CFRP strips [PDF]

open access: yes, 2009
[Excerpt] Introduction: Experimental [1], numerical and analytical [2] research reveals that as larger is the height of the cross section of Carbon Fiber Reinforced Polymer (CFRP) strip, as more effective is the Near Surface Mounted (NSM) technique for ...

Effect of Steel Fiber and Different Environments on Flexural Behavior of Reinforced Concrete Beams

open access: yesApplied Sciences, 2017
The main kind of deterioration in marine Reinforced Concrete (RC) structures and other infrastructures is steel bar corrosion due to cracks in concrete surfaces, which leads to the reduction of the load carrying capacity, ductility, and structural safety.

An improved closed-form solution to interfacial stresses in plated beams using a two-stage approach [PDF]

open access: yes, 2009
The shear stress and the normal stresses in the thickness direction at interfaces (referred as interfacial shear and transverse normal stresses hereafter) have played a significant role in understanding the premature debonding failure of beams ...

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

open access: yesAdvanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Ductility Tuning via Cluster Network Characteristics of Porous Components

open access: yesAdvanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Flux Analysis of the Supercapacitor Performance at Component Level

open access: yesAdvanced Materials Technologies, EarlyView.
The central objective of this study is to introduce new approach and metrics for analyzing the supercapacitor performance at the component level. The lack of standardized evaluation methodologies for analyzing the nonlinear behavior of real system is critical and hinders progress of supercapacitor.
