Anisotropic time-dependent behaviors of shale under direct shearing and associated empirical creep models

Journal of Rock Mechanics and Geotechnical Engineering
Understanding the anisotropic creep behaviors of shale under direct shearing is a challenging issue. In this context, we conducted shear-creep and steady-creep tests on shale with five bedding orientations (i.e.

Preliminary studies of the time-dependent shear and uniaxial tensile behaviour of oriented polymers [PDF]

, 1969
Summary The work reported in this memo is the initial stages of an investigation of the time-dependent behaviour of certain anisotropic polymers. In the first instance low density polyethylene with a transversely isotropic symmetry is being examined.

Boundary Effect Modeling In the Problem of Stochastic Heterogeneous Stripe Tension Under Creep

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009
The boundary effect in stochastic creep boundary problem of endless heterogeneous stripe tension was modeled. Determining creep factors which were applied in compliance with a nonlinear theory of viscid flow are formulated in a stochastic form.

Creep studies on oriented thermoplastics [PDF]

, 1969
The enhancement of many of the mechanical properties of thermoplastics which may be achieved by orienting the molecules has been known for some time. It has been exploited in the production of textile fibres end oriented films.

Linear Rheological Response of a Series of Densely Branched Brush Polymers [PDF]

, 2011
We have examined the linear rheological responses of a series of welldefined, dense, regularly branched brush polymers. These narrow molecular weight distribution brush polymers had polynorobornene backbones with degrees of polymerization (DP) of 200 ...

Static viscoelasticity of biomass polyethylene composites

Results in Physics, 2017
The biomass polyethylene composites filled with poplar wood flour, rice husk, cotton stalk or corn stalk were prepared by extrusion molding. The static viscoelasticity of composites was investigated by the dynamic thermal mechanical analyzer (DMA ...

A generalization of the Becker model in linear viscoelasticity: Creep, relaxation and internal friction

, 2018
We present a new rheological model depending on a real parameter $\nu \in [0,1]$ that reduces to the Maxwell body for $\nu=0$ and to the Becker body for $\nu=1$.
