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

open access: yesFrontiers 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

open access: yes, 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.

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

open access: yes, 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

open access: yes, 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]

open access: yes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 ...

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

open access: yesJournal 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

open access: yesFrontiers 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.
