Uniaxial tests on frozen loess and its constitutive model

Yantu gongcheng xuebao, 2017
The loading rate and temperature have great influences on the strength and deformation behaviors of frozen soil. A series of mechanical tests on frozen loess, including constant-strain-rate uniaxial tests, strain-rate jump tests and loading-unloading ...

Strain rate and temperature dependence of Omori law scaling constants of AE data: Implications for earthquake foreshock-aftershock sequences [PDF]

, 2004
Little is known about the temperature and strain rate dependence of acoustic emission AE activity (AE). Hence, we carried out a preliminary series of flow-through triaxial compression tests on porous sandstones at different temperatures and strain rates.

Particle Diffusion in Slow Granular Bulk Flows [PDF]

, 2012
We probe the diffusive motion of particles in slowly sheared three dimensional granular suspensions. For sufficiently large strains, the particle dynamics exhibits diffusive Gaussian statistics, with the diffusivity proportional to the local strain rate -

Strain rate dependency of fractures of immature bone

Journal of the Mechanical Behavior of Biomedical Materials, 2017
Radiological features alone do not allow the discrimination between accidental paediatric long bone fractures or those sustained by child abuse. Therefore, there is a clinical need to elucidate the mechanisms behind each fracture to provide a forensic biomechanical tool for the vulnerable child.

Precipitation size and strain rate dependence of dislocation-amorphous nanopillar interaction mechanism in magnesium

Journal of Materials Research and Technology, 2023
Introducing amorphous phases into the crystalline matrix is a new design strategy to improve the mechanical properties of Mg alloys. In this work, the effects of strain rate and amorphous nanopillar size on the interaction mechanism between the ...

Strain-Rate Dependence of Plasticity and Phase Transition in [001]-Oriented Single-Crystal Iron

Crystals, 2023
Non-equilibrium molecular dynamics simulations have been used to investigate strain-rate dependence of plasticity and phase transition in [001]-oriented single-crystal iron under ramp compression.

Decoherence of a quantum two-level system by spectral diffusion

, 2016
We study the dephasing of an individual high-frequency tunneling two-level system (TLS) due to its interaction with an ensemble of low-frequency thermal TLSs which are described by the standard tunneling model (STM).

Loading Rate Dependence of Rock Strength Under Triaxial Compression

Frontiers in Earth Science, 2021
Knowledge regarding the time-dependent behavior of rocks is essential to estimate the long-term deformation and stability of underground structures. The rock strength increases with the increasing loading rate.

A framework for analyzing hyper-viscoelastic polymers

, 2017
Hyper-viscoelastic polymers have multiple areas of application including aerospace, biomedicine, and automotive. Their mechanical responses are therefore extremely important to understand, particularly because they exhibit strong rate and temperature ...

Strain Rate Dependence of PLC Effect in AlMg4.5 Alloys

Engineering Proceedings
Tensile tests of AlMg4.5 alloy were carried out at six strain rates to study the Portevin–Le Chatelier (PLC) effect. The measured engineering stress–time and engineering stress–engineering strain curves were evaluated by direct peak detection and ...
