Relaxation phenomena of electrical signal emissions from rock following application of abrupt mechanical stress
mechanical stress PSC amphibolite
2015/8/24
The emission of electrical signals during application of mechanical stress to brittle geo-materials (the so-called pressure-stimulated current; PSC) can provide significant information regarding the m...
The Effection of Stress Path on the Rock Relaxation Area of Large-Section Tunnel
Large Section Tress-Path Numerical Simulation Tunnel Relaxation-Areas
2011/12/21
Construction of large-section tunnel leads to changing of rock stress and comes about complicated stress-path, which causes continuously redistribution of rock stress with changing of stress path, lea...
Dielectric-Relaxation Spectroscopy of Kaolinite, Montmorillonite, Allophane, and Imogolite under Moist Conditions
Allophane Bound Water Complex Permittivity Dielectric-Relaxation Spectroscopy Imogolite Interfacial Polarization Kaolinite Montmorillonite Time-Domain Reflectometry
2011/12/2
Abstract: The dielectric behavior of kaolinite, montmorillonite, allophane, and imogolite samples adjusted to a water potential of 33 kPa was examined using a time-domain reflectometry method over a w...

The Birefringent Orientation and Relaxation of Clay Platelets as Affected by Particle Size, Saturating Cation and Clay Type
Birefringent Orientation Relaxation Clay Platelets Clay Type
2012/2/13
Previous work has shown that some clay particles orient at both low and high voltages due to a permanent dipole and an induced dipole, respectively, whereas other clays under similar short-duration pu...
