Near surface mounted thecnique for the flexural and shear strengthening of concrete beams [PDF]

open access: yes, 2005
The efficacies of the Near Surface Mounted and Externally Bonded Reinforcing techniques for the flexural and shear strengthening of reinforced concrete beams are compared. Both techniques are based on the use of carbon fiber reinforced polymer materials.

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

open access: yesAdvanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Upgrading of Deficient Disturbed Regions in Precast RC beams with Near Surface Mounted (NSM) Steel Bars

open access: yesJournal of Materials and Engineering Structures, 2020
An experimental study has been conducted to explore the response of self-compacting RC drop in- beams retrofitted with NSM steel bars under short-term static loading. Eleven specimens have been tested in this program, each of (200x400x1600 mm) dimensions

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Computation of three-dimensional shock wave and boundary-layer interactions [PDF]

open access: yes
Computations of the impingement of an oblique shock wave on a cylinder and a supersonic flow past a blunt fin mounted on a plate are used to study three dimensional shock wave and boundary layer interaction.

Analysis of the bond between near-surface mounted CFRP laminate strips and concrete [PDF]

open access: yes, 2005
The flexural and the shear resistance of concrete, masonry and timber structures can be efficiently increased using near-surface mounted (NSM) CFRP laminate strips.

Strengthening of prism beam by using NSM technique with roots planted in concrete [PDF]

open access: yes, 2017
This paper presents experimental results of four prismatic concrete reinforced beam and strengthened by NSM (Near surface mounted) FRP (Fiber Reinforced Polymer) reinforced technique, with additional roots planted in the concrete.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
