Shear critical R/C columns under increasing axial load [PDF]

, 2020
Structural elements in old reinforced concrete (R/C) frame buildings are often prone to shear or flexure-shear failure, which can eventually lead to loss of axial load capacity of vertical elements and initiate vertical progressive collapse of a building.

A shear brittleness index for rock joints and its application in direct shear failure analysis

Results in Engineering
The brittle shear failure of rock mass structural planes is an important cause of structure-controlled rockburst, which severely threatens the safety construction of deep rock engineering.

The Shear Response of Beryllium as a Function of Temperature and Strain Rate

EPJ Web of Conferences, 2018
A new specimen design has been developed to measure the shear response of materials. This compact forced-simple-shear specimen (CFSS) has been utilized to measure the shear stress/shear strain response of other materials [1, 2]. Earlier, unpublished work

Analysis of Influence of Strata Dip Angle on Shear Deformation of Drilling Casing

Meikuang Anquan, 2020
Aiming at the shear failure of drilling casing, based on the movement law of overlying strata in coal seam mining, the finite element model of shear deformation of drilling casing is established by ANSYS numerical simulation software, and the effect of ...

Size-independent Shear Band Formation in Amorphous Nanowires made from Simulated Casting

, 2010
Molecular dynamics simulations indicate that surfaces strongly influence the strain localization behavior of amorphous nanowires in tension. A sample preparation routine that simulates casting was employed to facilitate the relaxation of the sample ...

$1/f$ noise and avalanche scaling in plastic deformation [PDF]

, 2006
We study the intermittency and noise of dislocation systems undergoing shear deformation. Simulations of a simple two-dimensional discrete dislocation dynamics model indicate that the deformation rate exhibits a power spectrum scaling of the type $1/f ...

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Neo-Hookean fiber composites undergoing finite out-of-plane shear deformations

, 2005
The response of a neo-Hookean fiber composite undergoing finite out-of-plane shear deformation is examined. To this end an explicit close form solution for the out-of-plane shear response of a cylindrical composite element is introduced. We find that the

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

In-situ EBSD observation of texture evolution and lattice rotation behavior in shear deformation of thin-walled aluminum alloy tubes

Journal of Materials Research and Technology
As shear stress plays a significant role in the deformation of tubular parts with complex shapes, investigation of the microstructue evolution of tubes under the shear stress state is beneficial to understanding the shear deformation mechanism and ...
