This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

TENSILE CAPACITIES OF CFRP ANCHORS
In reinforced concrete buildings inserting adequate amount of reinforced concrete infills is an effective strengthening technique. Another promising technique is to strengthen the existing hollow clay tile infill with diagonally placed CFRP sheets. In this technique, CFRPsheets are extended to the frame members.

This study elucidates the microstructural evolution at the material interface of Ni‐plated plain‐weave carbon fiber fabric following vacuum heat treatment at 500°C–900°C under different current densities, as well as the mechanism underlying the synergistic enhancement of electromagnetic shielding and ductility.

Increase of bending strength and maximum deflection of concrete reinforced with CFRP strips
In 1981, many detached houses collapsed owing to the earthquake which took place at the coast of Miyagi Prefecture in Japan, because ferroconcrete was not used as the base of most of the collapsed houses.

Effects of CFRP sheets on the flexural behavior of high-strength concrete beam
The aim of this study is to evaluate numerically the effects of carbon fiber-reinforced polymer (CFRP) sheets strengthening on the flexural performance of high-strength concrete (HSC) beam using ABAQUS 3D finite element (FE) modeling software.

The impact of using prestressed CFRP bars on the development of flexural strength
The load-carrying capacity and ductility of conventional steel reinforcement may be greatly increased by using ordinary and prestressed carbon fiber-reinforced polymer (CFRP) bars, resulting in reinforced concrete structures with greater sturdiness. This
