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

open access: yesE3S 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

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

open access: yesOcean 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

open access: yesFracture 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

open access: yesFrontiers 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

open access: yesMeikuang 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]

open access: yesE3S 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 ...

A vortex-based subgrid stress model for large-eddy simulation [PDF]

open access: yes, 1997
A class of subgrid stress (SGS) models for large-eddy simulation (LES) is presented based on the idea of structure-based Reynolds-stress closure. The subgrid structure of the turbulence is assumed to consist of stretched vortices whose orientations are ...

Response of interior beam-column connections integrated with various schemes of CFRP composites

open access: yesCase Studies in Construction Materials, 2021
This study evaluates the effectiveness of integrating Carbon Fiber Reinforced Polymer (CFRP) composites for improving the response of interior Beam-Column (B-C) connections under the combined effects of axial and lateral cyclic loads. Eighteen Reinforced
