Increasing weaning age of piglets from 4 to 7 weeks reduces stress, increases post-weaning feed intake but does not improve intestinal functionality [PDF]

open access: yes, 2010
This study tested the hypothesis that late weaning and the availability of creep feed during the suckling period compared with early weaning, improves feed intake, decreases stress and improves the integrity of the intestinal tract.

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

Study on Creep Behavior of Silty Clay Based on Fractal Derivative

open access: yesApplied Sciences, 2022
Soft soil is widely distributed in the riverside area of southern China. The creep deformation characteristics of the soft soil affect the long-term stability of the structure foundation, which cannot be ignored. Through the triaxial drainage creep test,

Time-Dependent Creep Constitutive Model of Roadway Surrounding Rock Based on Creep Parameters

open access: yesGeofluids, 2022
In order to better study the creep deformation characteristics of rock under different stresses, the generalized Burgers model was used as the basic model after analyzing the creep characteristics of rock and its relationship with stress and strain, and ...

A novel nonlinear creep model based on damage characteristics of mudstone strength parameters.

open access: yesPLoS ONE, 2021
Mudstone interlayer is a weak layer in rock engineering. When it is subjected to continuous stress higher than its damage threshold, due to the dislocation of particles in mudstone crystals and the expansion of cracks, mudstone strength is gradually ...

Flux creep in type-II superconductors: self-organized criticality approach

open access: yes, 2004
We consider the current density distribution function of a flux creep regime in type-II superconductors by mapping the flux creep process to the dynamics of a model with a self-organized criticality. We use an extremal Robin Hood type model which evolves

The creep behavior of simple structures with a stress range-dependent constitutive model [PDF]

open access: yes, 2012
High temperature design remains an issue for many components in a variety of industries. Although finite element analysis for creep is now an accessible tool, most analyses outside the research domain use long standing and very simple constitutive models

Experimental study on creep failure characteristics of coal mass under multistage stress and construction of prediction model

open access: yesFrontiers in Earth Science, 2023
The creep and failure mode of stratified coal is complex and challenging to predict. This is highly attributed to the internal stratified structure generated during coal forming.

Creep motion of an elastic string in a random potential

open access: yes, 2004
We study the creep motion of an elastic string in a two dimensional pinning landscape by Langevin dynamics simulations. We find that the Velocity-Force characteristics are well described by the creep formula predicted from phenomenological scaling ...

Application of time–stress superposition to viscoelastic behavior of polyamide 6,6 fiber and its “true” elastic modulus [PDF]

open access: yes, 2017
The viscoelastic behavior of semi-crystalline polyamide 6,6 fiber is exploited in viscoelastically prestressed polymeric matrix composites. To understand better the underlying prestress mechanisms, strain–time performance of the fiber material is ...
