Magnetic relaxation and collective vortex creep in FeTe$_{0.6}$Se$_{0.4}$ single crystal [PDF]

open access: yesEPL, 103 (2013) 57013, 2013
We study the vortex dynamics in high-quality FeTe$_{0.6}$Se$_{0.4}$ single crystal by performing magnetization measurements of the screening current density \emph{J}$_s$ and flux creep rate \emph{S}. Temperature dependence of \emph{S} shows a plateau in the intermediate temperature region with a high creep rate $\sim$ 0.03, which is interpreted in the ...

Theory of plastic vortex creep [PDF]

open access: yesPhys. Rev. Lett. 85, 4948 (2000), 2000
We develop a theory for plastic flux creep in a topologically disordered vortex solid phase in type-II superconductors. We propose a detailed description of the plastic vortex creep of the dislocated, amorphous vortex glass in terms of motion of dislocations driven by a transport current $j$.

Creep rupture of materials: insights from a fiber bundle model with relaxation [PDF]

open access: yes, 2010
I adapted a model recently introduced in the context of seismic phenomena, to study creep rupture of materials. It consists of linear elastic fibers that interact in an equal load sharing scheme, complemented with a local viscoelastic relaxation mechanism.

Creep failure characteristics and damage creep model of red layer soft rock based on Perzyna viscoplastic theory [PDF]

open access: yesScientific Reports
Rock creep is essentially a process of damage accumulation. According to the damage evolution of rock under creep conditions, the TAW2000 triaxial test system is used to carry out triaxial creep test on red layer soft rock taken from Yibo Tunnel in ...

Rubber Creep Model and Its Influence on Mounting Stiffness

open access: yesApplied Sciences, 2022
The mount of the engine will creep under the action of long-term load. Creep will change its original structure, resulting in changes in static and dynamic characteristics and fatigue life.

Triaxial creep test and model study of red sandstone based on Weibull distribution

open access: yesShuiwen dizhi gongcheng dizhi, 2023
At present, the creep problem of underground engineering surrounding rock still exists, and the creep theory needs to be further enriched. In essence, rock creep is a process of constant accumulation of damage.

Determination of the parameters of rock viscoelastic creep model and analysis of parameter degradation

open access: yesScientific Reports, 2023
Different stress creep tests are conducted on the sandstone in this study to better describe the creep properties of rocks under different stress states. A model that describes the rock creep process is established.

Long-term creep law and constitutive model of extremely soft coal rock subjected to single-stage load

open access: yesRock and Soil Mechanics, 2021
In order to study the long-term creep law of extremely soft coal rock, the uniaxial and triaxial creep tests of extremely soft coal rock subjected to single-stage loads were carried out by using the self-developed triaxial creep test system.

Analysis of Shear Characteristics of Deep, Anchored Rock Mass under Creep Fatigue Loading

open access: yesAdvances in Civil Engineering, 2021
To study the influence of earthquakes and engineering disturbances on the deformation of deeply buried rock masses, shear tests were carried out on anchored sandstone rock masses, anchored marble rock masses, and anchored granite rock masses under creep ...

A unified constitutive model for asymmetric tension and compression creep-ageing behaviour of naturally aged Al-Cu-Li alloy [PDF]

open access: yes, 2016
A set of unified constitutive equations is presented that predict the asymmetric tension and compression creep behaviour and recently observed double primary creep of pre-stretched/naturally aged aluminium-cooper-lithium alloy AA2050-T34.
