Accelerated Creep of Asphalt Concrete at Medium Temperatures

open access: yesApplied Sciences
In this paper, the accelerated creep under uniaxial tension of hot fine-grained dense asphalt concrete at temperatures of 22–24 °C and stresses from 0.084 MPa to 0.596 MPa is experimentally investigated.

Vertebral deformity arising from an accelerated "creep" mechanism. [PDF]

open access: yesEur Spine J, 2012
Vertebral deformities often occur in patients who recall no trauma, and display no evident fracture on radiographs. We hypothesise that vertebral deformity can occur by a gradual creep mechanism which is accelerated following minor damage. "Creep" is continuous deformation under constant load.Forty-five thoracolumbar spine motion segments were tested ...

Research on the evolution characteristics of creep energy in rubber concrete and the damage constitutive model [PDF]

open access: yesScientific Reports
To investigate the evolution law of energy and the damage constitutive model of concrete with different rubber replacement ratios under uniaxial creep, this paper systematically studied the creep energy evolution law of rubber concrete using uniaxial ...

Creep constitutive model of strain energy density considering the whole process of creep deformation. [PDF]

open access: yesPLoS ONE
Aiming at the problem that the traditional creep model is difficult to reflect the characteristics of accelerated creep stage of rock, the influence of stress state on accelerated creep is fully considered, and a constitutive model which can describe ...

Accelerated testing of creep in polymeric materials using nanoindentation

open access: yesPolymer Testing, 2011
Abstract Creep properties of polymers are conventionally obtained from tensile creep tests but, due to the different processing conditions used in their manufacture, the microstructure and properties of the specimens used in this type of test are often different to those found in actual components.

Creep model of roadway surrounding rock considering hardening effect and damage effect. [PDF]

open access: yesPLoS ONE
The influence of confining pressure on creep characteristics was analyzed by carrying out creep tests of rocks under different confining pressures. A new creep model of roadway surrounding rock considering the combined influence of hardening effect and ...

Creep characteristics of muddy siltstone and its engineering application on cross-river tunnel stability [PDF]

open access: yesScientific Reports
Muddy siltstone combines the characteristics of both sandstone and mudstone, and is prone to instability over time. To study the long-term stability of tunnel engineering in this stratum, this article taking the cross-river metro tunnel section as the ...

A nonlinear creep model for surrounding rocks of tunnels based on kinetic energy theorem

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
The initiating condition for the accelerated creep of rocks has caused difficulty in analyzing the whole creep process. Moreover, the existing Nishihara model has evident shortcomings in describing the accelerated creep characteristics of the ...

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.

Study on the Creep of Damage-Containing Anthracite: Theory and Experiment

open access: yesApplied Sciences, 2023
Fractal derivatives characterize the accelerated creep phase of the creep process. In this study, based on the fractal order theory, the integer-order derivatives are defined from the spatio-temporal self-similarity phenomenon of the dynamic process ...
