Experimental study on strength and failure characteristics of mortar specimens with prefabricated cracks under uniaxial and triaxial stress

Frontiers in Materials, 2023
Cracks in rock masses have adverse effects on their mechanical characteristics and the stability of rock mass engineering. For this experiment, uniaxial compression and true triaxial compression unloading tests were conducted on mortar specimens.

Suppression of hole-hole scattering in GaAs/AlGaAs heterostructures under uniaxial compression

, 1998
Resistance, magnetoresistance and their temperature dependencies have been investigated in the 2D hole gas at a [001] p-GaAs/Al$_{0.5}$Ga$_{0.5}$As heterointerface under [110] uniaxial compression.

Strain Hardening of Polymer Glasses: Entanglements, Energetics, and Plasticity [PDF]

, 2008
Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While stress-strain curves for a wide range of temperature can be fit to the functional form predicted by entropic network models, many other results are ...

Phase diagram of hard board like colloids from computer simulations [PDF]

, 2013
The rich mesophase polymorhism and the phase sequence of board-like colloids depends critically on their shape anisometry. Implementing extensive Monte Carlo simulations, we calculated the full phase diagram of sterically interacting board-like particles,

Uniaxial Phase Transition in Si : Ab initio Calculations

, 2002
Based on a previously proposed thermodynamic analysis, we study the relative stabilities of five Si phases under uniaxial compression using ab initio methods. The five phases are diamond, beta-tin, sh, sc, and hcp structures.

Mechanical Properties of Low-carbon Ultra-high Performance Concrete under Uniaxial Compression [PDF]

长江科学院院报
To tackle the high carbon emissions issue resulting from doubling the cement dosage in ultra-high performance concrete (UHPC), a low-carbon ultra-high performance concrete (LC-UHPC) was developed by replacing a large proportion of Portland cement with ...

Band gap engineering of MoS$_2$ upon compression [PDF]

, 2016
Molybdenum disulfide (MoS$_2$) is a promising candidate for 2D nanoelectronic devices, that shows a direct band-gap for monolayer structure. In this work we study the electronic structure of MoS$_2$ upon both compressive and tensile strains with first ...

A methodology to determine the elastic properties of anisotropic rocks from a single uniaxial compression test

Journal of Rock Mechanics and Geotechnical Engineering, 2019
This paper introduces a new methodology to measure the elastic constants of transversely isotropic rocks from a single uniaxial compression test. We first give the mathematical proof that a uniaxial compression test provides only four independent strain ...

A Constitutive Model for Cemented Tailings Backfill Under Uniaxial Compression

Frontiers in Physics, 2020
Constitutive model is the foundation describing the mechanical properties of materials. Cemented tailings backfill (CTB) plays an important role in goaf filling. However, a universally applicable constitutive model for CTB has not been proposed yet.
