Description of Concrete Creep under Time-Varying Stress Using Parallel Creep Curve
Advances in Materials Science and Engineering, 2016 An incremental format of creep model was presented to take account of the development of concrete creep due to loading at different ages. The formulation was attained by introducing a horizontal parallel assumption of creep curves and combining it with ...

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

Extruded Mg based hybrid composite alloys studied by longitudinal impression creep [PDF]
Composites Science and Technology, 68, 3251 (2008), 2017 The creep behaviour of a creep-resistant AE42 magnesium alloy reinforced with Saffil short fibres and SiC particulates in various combinations has been examined in the longitudinal direction, i.e., the plane containing random fibre orientation was parallel to the loading direction, in the temperature range of 175-300 C at the stress levels ranging from

Nanoscale creep mechanism of clay through MD modeling with hexagonal particles [PDF]
arXiv, 2023 In this article, we investigate the creep mechanism of clay at the nanoscale. We conduct the molecular dynamics (MD) modeling of clay samples consisting of hexagonal particles under compression and shear. The MD simulations include oedometer creep, shear creep, direct shear tests, and stress relaxation.

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

Mechanical Creep Instability of Nanocrystalline Methane Hydrates [PDF]
, 2020 Mechanical creep behaviors of natural gas hydrates (NGHs) are of importance for understanding mechanical instability of gas hydrate-bearing sediments on Earth. Limited by the experimental challenges, intrinsic creep mechanisms of nanocrystalline methane hydrates remain largely unknown yet at molecular scale. Herein, using large-scale molecular dynamics

History effects in the creep of a disordered brittle material [PDF]
arXiv, 2022 We study the creep behavior of a disordered brittle material (concrete) under successive loading steps, using acoustic emission and ultrasonic sensing to track internal damage. The primary creep rate is observed to follow a (Omori-type) power-law decay in the strain rate, the number of acoustic emission events as well as the amplitudes of the ...

An elastic-viscoplastic creep model for describing creep behavior of layered rock
Frontiers in Materials, 2023 To describe the full-stage creep behavior of layered rock accurately, a new elastic-viscoplastic creep model is proposed based on fractional order theory in this manuscript, which consists of a Hooke elastomer, a fractional Abel dashpot, a Kelvin body ...
