Constraining an eddy energy dissipation rate due to relative wind stress for use in energy budget-based eddy parameterisations [PDF]

Ocean Science, 2023
A geostrophic eddy energy dissipation rate due to the interaction of the large-scale wind field and mesoscale ocean currents, or relative wind stress, is derived here for use in eddy energy budget-based eddy parameterisations.

The effect of temperature on low-cycle fatigue of shape memory alloy

Fracture and Structural Integrity, 2019
The influence of temperature on the fatigue properties of pseudoelastic NiTi under low-cycle fatigue are investigated. Tests were performed under the uniaxial tensile deformation (pull-pull) at 0 ? and 20 ? which is above the austenite finish temperature.

Creep crack energy dissipation and instability prediction in micritic bioclastic limestone

Frontiers in Earth Science, 2023
Time-dependent deformation and long-term stability of rocks are important issues in water conservancy and geotechnical engineering. Currently, there are no well-accepted theoretical criteria with which to predict stability and damage considering time ...

Energy Variation Rules of Gas Hydrate-bearing Coal Under Conventional Triaxial Compression

Meikuang Anquan, 2020
This study focuses on the energy variation rules of gas hydrate-bearing coal during deformation and failure, combined with the deviatoric stress-strain curves under conventional triaxial compression and the first law of thermodynamics.

The short DMTA dissipation test [PDF]

E3S Web of Conferences
The CPT is used either in a continuous advance mode or in a rheological testing mode. Both periods are present in the short local side friction and in the short cone resistance dissipation tests made in the technical breaks of continuous penetration of ...

Least-Squares evaluation of DMT dissipation test data – some preliminary results [PDF]

E3S Web of Conferences
The Flex method does not work if the DMTA total stress dissipation curve is non-monotonic or has no inflexion point. To overcome the problems, various versions of a mathematically precise DMTA total stress dissipation test evaluation method are suggested

Coupled models for total stress dissipation tests

, 2021
Two linear, point-symmetric, coupled consolidation model families with various embedding space dimension values (oedometer models - 1, spherical models - 3, cylindrical models - 2), differing in one boundary condition (coupled 1 - constant displacement, coupled 2 - constant stress) are analysed analytically and numerically.

Protective Effects of Selenium on Wheat Seedlings under Salt Stress

Agronomy, 2019
Wheat is a staple food worldwide, but its productivity is reduced by salt stress. In this study, the mitigative effects of 22 μM selenium (Se) on seedlings of the wheat (Triticum aestivum L.) cultivar Taichung SEL.
