Pseudoelastic behaviour of cast magnesium AZ91 alloy under cyclic loading–unloading
Acta Materialia, 2003Large stress-strain hysteresis loops are observed under cyclic loading after a small plastic prestrain. Loops have been observed in sand-cast material in a variety of tempers under tension or compression, and in high-pressure die-cast material with different cross-section thickness tested in tension.

The mechanical properties of rock salt under cyclic loading-unloading experiments
Geomechanics and Engineering, 2016Rock salt is a near-perfect material for gas storage repositories due to its excellent ductility and low permeability. Gas storage in rock salt layers during gas injection and gas production causes the stress redistribution surrounding the cavity. The triaxial cyclic loading and unloading tests for rock salt were performed in this paper.

Permeability Characteristics of Broken Coal and Rock Under Cyclic Loading and Unloading
Natural Resources Research, 2018During longwall mining, the permeability evaluation in a caving zone is one of the most challenging risks for mine operators because it controls the behavior of gas flow and it significantly influences gob gas extraction and spontaneous combustion. Based on the stress environment of repeated mining in the Huainan coal mine, this study discusses the ...

Effects of Detwinning on the Inelasticity of AZ31B Sheets During Cyclic Loading and Unloading
International Journal of Applied Mechanics, 2018Magnesium alloys exhibit significant inelastic behavior during unloading, especially when twinning and detwinning are involved. It is commonly accepted that noteworthy inelastic behavior will be observed during unloading if twinning occurs during previous loading. However, this phenomenon is not always observed for Mg sheets with strong rolled texture.

Progressive weakening of zeolite granules due to cyclic moisture loading and unloading
Microporous and Mesoporous Materials, 2015Abstract The influence of moisture content and cyclic moisture loading and unloading on the mechanical properties like the strength of three different types of zeolite granules has been studied by uniaxial compression tests. The tested granules had been processed using different contents of binder and different thermal drying/activation temperatures.

The axial and radial permeability testing of coal under cyclic loading and unloading
Arabian Journal of Geosciences, 2019Porous reservoir rocks are often anisotropic in permeability. It is necessary, therefore, to study the effect of anisotropy on the permeability of porous coal seams that are subjected to stress during repeated mining of grouped coal seams. In the present investigation, specialized permeability evaluation equipment, known as gas injection to flush ...
