Damaged RC beams strengthened with GFRP

Procedia Structural Integrity, 2018
Abstract In recent years one of the most important duty of civil engineers is to define methods of rehabilitation both for historic and modern structures. Reinforced concrete is a relatively modern material of construction and it is often damaged both with cracking due to loading or corrosion of reinforcement.

Ductility Tuning via Cluster Network Characteristics of Porous Components

Advanced 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

Performance of pre-cracked RC beams shear strengthened with NSM CFRP laminates [PDF]

, 2012
The strengthening of an existing Reinforced Concrete (RC) structure often involves concrete in a cracked state. To evaluate the effect of existing cracks on the behavior of RC beams shear strengthened according to the Near Surface Mounted (NSM) technique

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Flux Analysis of the Supercapacitor Performance at Component Level

Advanced 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.
