Cyclic Triaxial Test of Dynamic Soil Properties for Wide Strain Range

Soils and Foundations, 1980
ABSTRACT Dynamic material properties of soil needed for the nonlinear analysis of earthquake response of the ground have usually been measured in the laboratory using the torsional column shear device. The cyclic triaxial test, despite its easier accessibility and handling for practicing engineers, has seldom been looked upon as a rational way to ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Resilient Modulus of Recycled Aggregates Obtained by Means of Dynamic Tests in a Triaxial Apparatus

Procedia - Social and Behavioral Sciences, 2012
AbstractThe main objective of this experimental research is to prove the hypothesis of the use of recycled materials (C&D) in building road subbases by means of a comparative study which investigates the resilient behaviour of unbound aggregate blends.The results given by the investigation clearly prove that the blend made of recycled materials has ...

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment

Equine Veterinary Journal, EarlyView.
Abstract Background Lineage‐based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline‐specific locomotor behaviour under standardised conditions remains limited.
