Anomalous acoustic reflection on a sliding interface or a shear band [PDF]
, 2003 We study the reflection of an acoustic plane wave from a steadily sliding planar interface with velocity strengthening friction or a shear band in a confined granular medium.

An experimental investigation for external RC shear wall applications [PDF]
Natural Hazards and Earth System Sciences, 2010 The strength and rigidity of most reinforced concrete (RC) buildings in Turkey, which are frequently hit by destructive earthquakes, is not at a sufficient level. Therefore, the result of earthquakes is a significant loss of life and property.

Mechanisms for slow strengthening in granular materials [PDF]
, 1999 Several mechanisms cause a granular material to strengthen over time at low applied stress. The strength is determined from the maximum frictional force F_max experienced by a shearing plate in contact with wet or dry granular material after the layer ...

Rate dependent shear bands in a shear transformation zone model of amorphous solids [PDF]
, 2008 We use Shear Transformation Zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation.

FRCM SHEAR STRENGTHENING FOR CONCRETE BEAMS
Proceedings of International Structural Engineering and Construction, 2017 This paper presents the results of an experimental study carried out to examine the efficacy of Fabric-Reinforced Cementitious Matrix (FRCM) in strengthening RC beams susceptible to shear failure. In this paper, seven shear-critical RC beams, of 2,500 mm in length, 150 mm in width, and 330 mm in depth, were tested under three-point loading until ...

Direct shear strengthening of NSC and SCC using NSM CFRP and steel bars
Sulaimani Journal for Engineering Sciences, 2020 Failure in direct shear is sudden and catastrophic in concrete structures, Several techniques have been developed for shear strengthening of push-off specimens representing direct shear. In this research, the effectiveness of Near-surface mounted

Shear thickening in densely packed suspensions of spheres and rods confined to few layers [PDF]
, 2010 We investigate confined shear thickening suspensions for which the sample thickness is comparable to the particle dimensions. Rheometry measurements are presented for densely packed suspensions of spheres and rods with aspect ratios 6 and 9.

Elastic analysis of adhesion stresses for the design of a strengthening plate bonded to a beam [PDF]
, 2006 This paper presents methods for determining the elastic shear and peel stresses in an adhesive joint between a strengthening plate and a beam. Both closed-form and finite-difference solutions are given, allowing loading, temperature effects and plate ...
