Rheology and Shear Band Suppression in Particle and Chain Mixtures

open access: yes, 2012
Using numerical simulations, we consider an amorphous particle mixture which exhibits shear banding, and find that the addition of even a small fraction of chains strongly enhances the material strength, creating pronounced overshoot features in the ...

Seismic performance of shear-critical RC columns strengthened by multiple composites considering shifted failure zone

open access: yesCase Studies in Construction Materials
Strengthening reinforced concrete (RC) columns utilizing advanced composites, including fiber-reinforced polymer (FRP), polyethylene terephthalate (PET) FRP, and engineered cementitious composite (ECC) has attracted extensive efforts for decades ...

Static and sliding contact of rough surfaces: effect of asperity-scale properties and long-range elastic interactions [PDF]

open access: yes, 2018
Friction in static and sliding contact of rough surfaces is important in numerous physical phenomena. We seek to understand macroscopically observed static and sliding contact behavior as the collective response of a large number of microscopic ...

BOND AND SHEAR-STRENGTHENING PERFORMANCE OF FRCM COMPOSITES

open access: yesProceedings of International Structural Engineering and Construction, 2019
This paper is aimed at studying the bond and shear-strengthening performance of fabric reinforced cementitious matrix (FRCM) systems. Three FRCM systems were compared, namely, polyparaphenylene benzobisoxazole (PBO)-FRCM, Carbon-FRCM, and Glass-FRCM. At first, six double-shear specimens were tested to investigate the FRCM/concrete bond, with the test ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Flexural and Shear Strengthening of Reinforced-Concrete Beams with Ultra-High-Performance Concrete (UHPC)

open access: yesConstruction Materials
Ultra-high-performance concrete (UHPC) is considered to be a promising material for the strengthening of damaged reinforced concrete (RC) members due to its high mechanical strength and low permeability.
