Creep Rate and Creep Model of Rockfill

open access: yesProcedia Engineering, 2012
AbstractDue to the test duration restriction, not only the creep strain but also the creep rate should be considered to establish the creep model of the rockfill. The creep rate decides whether the creep model deviates from the actual strain after the test duration.

Creep Properties and Creep Modelling of Guilin Red Clay

open access: yesApplied Sciences, 2023
In order to explore the creep characteristics of red clay under different pressures, the stress–strain curve and stress–strain–time curve of red clay under different pressures were obtained, and the triaxial shear and creep characteristics of red clay under different pressures were analysed.

A simple model for tertiary creep in geomaterials [PDF]

open access: yesGeotechnical Research, 2020
This paper presents a constitutive modelling approach for the viscoplastic-damage behaviour of geomaterials. This approach is based on the hyperelasticity framework, where the entire constitutive behaviour is derived from only two scalar potentials: a free-energy potential and a dissipation function.

Influence of constitutive model on calculation results of creep deformation response of notched specimen of GH4169 alloy

open access: yesJournal of Aeronautical Materials, 2021
In view of the creep deformation failure of areo-engine high temperature components, the elastoplastic and creep deformation response of GH4169 alloy smooth and notched plate specimens at 650 ℃ is calculated using elastoplastic coupled creep constitutive

Creep Characteristic Test and Creep Model of Frozen Soil

open access: yesSustainability, 2023
In order to research the creep deformation characteristics of frozen soil and the effect of various influencing factors on creep, indoor uniaxial creep tests were carried out on frozen soil specimens at temperatures of −5, −4, −3 and −2 °C under loads of 0.25, 0.5, and 0.75 σt, respectively.

Shear creep mechanical properties and damage model of mudstone in open-pit coal mine

open access: yesScientific Reports, 2022
Clarifying the shear creep characteristics of rock and scientifically analyzing its creep deformation law is the key to solving the problem of safe construction and long-term stability analysis of the open-pit coal slope rock mass. Shear creep tests were

A Comprehensive Creep Model

open access: yesJournal of Basic Engineering, 1967
Based on Dorn’s creep theory, a comprehensive creep model has been developed that is applicable to the calculation of deformation processes at steadily increasing temperatures and slowly varying load. It is shown that the entire course of the creep curve (excepting the tertiary creep) of structural (polycrystalline) materials is uniquely determined by ...

Creep Model and Experimental Verification of Sandstone under the Coupled Effect of Chemical Corrosion and Temperature

open access: yesApplied Sciences
The Nishihara creep model is an extremely effective method in the field of sandstone creep model research. However, the Nishihara creep model curve for sandstone under the marine environment (the coupled effect of chemical corrosion and temperature) does

Time-scale effect of the creep model parameters and particle flow simulation of sandstone with a single crack

open access: yesYantu gongcheng xuebao, 2019
The creep deformation behaviors of the hard rocks in deep high-stress environment, especially for the fractured hard rocks, cannot be neglected. To investigate the long-term creep deformation behaviors and the creep model for the fractured hard rock, the
