Characteristics and modelling of coral sand particle breakage under principal stress axis rotation

Soils and Foundations
To investigate the stress–strain characteristics and particle breakage laws of coral sand under the rotation of the principal stress axis—Objectives, the triaxial test and the principal stress axis rotation test were conducted on coral sand with varying ...

Constitutive modeling of anisotropic and non-coaxial behaviors of sand

Yantu gongcheng xuebao, 2018
A non-coaxial constitutive model is proposed from the elasto-plastic constitutive model based on the state-dependent critical state model considering the fabric anisotropy of sand.

Rotator and extender ferroelectrics: Importance of the shear coefficient to the piezoelectric properties of domain-engineered crystals and ceramics

, 2007
The importance of a high shear coefficient d15 (or d24) to the piezoelectric properties of domain-engineered and polycrystalline ferroelectrics is discussed.

Crustal stress field in southern California and its implications for fault mechanics [PDF]

, 2001
We present a new, high spatial resolution image of stress orientation in southern California based on the inversion of earthquake focal mechanisms. We use this image to study the mechanics of faulting in the plate boundary region.

Characteristics of Mining-Induced Stress Rotation Due to Unloading in Deep Roadway Excavation and Surrounding Rock Control Countermeasures

Applied Sciences
As metal mines advance into deep mining, the increase in tectonic stress and horizontal stress leads to a higher degree of joint and fissure development in roadway surrounding rocks, along with a significant rise in both the fragmentation degree of the ...

Testing of Undrained Shear Strength in a Hollow Cylinder Apparatus

Studia Geotechnica et Mechanica, 2015
The paper presents the results of tests performed in a Torsional Shear Hollow Cylinder Apparatus on undisturbed cohesive soils. The tests were performed on lightly overconsolidated clay (Cl) and sandy silty clay (sasiCl).

Improvement of Fourier Polarimetry for applications in tomographic photoelasticity [PDF]

, 2006
The use of the Fourier Polarimetry method has been demonstrated to extract the three characteristic parameters in integrated photoelasticity. In contrast to the phase-stepping method, it has been shown that the Fourier method is more accurate.

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.
