Analysis of properties of creep curves generated by the linear viscoelasticity theory under arbitrary loading programs at initial stage

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
The general equation of creep curves family generated by the linear integral constitutive relation of viscoelasticity (with an arbitrary creep compliance function) under arbitrary non-decreasing stress histories at initial stage of loading up to a given ...

Stress Dependency of Creep Response for Glass/Epoxy Composite at Nonlinear and Linear Viscoelastic Behavior

open access: yesInternational Journal of Polymer Science, 2022
This research is aimed at comparing the stress dependency of creep viscoelastic behavior for glass/epoxy composite and neat epoxy close to the glass transition temperature and room temperature.

Modeling of Tensile Creep and Recovery of Polymer Modified Asphalt Binders at Low Temperatures

open access: yesApplied Rheology, 2015
The creep and recovery of asphalt modified with Elvaloy 4170 and polyphosphoric acid were studied at low temperatures, by inductive phenomenological methods. Two models of the tensile compliance function were investigated.

Interaction between mechanosorptive and viscoelastic response of wood at high humidity level

open access: yesEPJ Web of Conferences, 2010
To clarify the contribution of mechanosorptive effect and compliance evolution according to moisture content during adsorption under load creep tests on longitudinal spruce specimens in variable environment were performed. By comparing different loading

Direct conversion of rheological compliance measurements into storage and loss moduli [PDF]

open access: yes, 2008
We remove the need for Laplace/inverse-Laplace transformations of experimental data, by presenting a direct and straightforward mathematical procedure for obtaining frequency-dependent storage and loss moduli ($G'(\omega)$ and $G"(\omega)$ respectively),

Lattice modelling of early-age creep of 3D printed segments with the consideration of stress history

open access: yesMaterials & Design, 2023
We propose a new numerical method to analyze the early-age creep of 3D printed segments with the consideration of stress history. The integral creep strain evaluation formula is first expressed in a summation form using superposition principle.

Probing polymer chain constraint and synergistic effects in nylon 6-clay nanocomposites and nylon 6-silica flake sub-micro composites with nanomechanics [PDF]

open access: yes, 2015
In this study, we report that a synergistic effect exists in the surface mechanical properties of nylon 6–clay nanocomposites (NC) that can be shown by nanomechanical testing.

Brittle Creep and Viscoelastic Creep in Lower Palaeozoic Shales from the Baltic Basin, Poland

open access: yesEnergies, 2021
The paper analyses the mechanical properties of shales from the Baltic Basin, focusing on creep strain in conditions of variable stress and elevated temperature (85 °C). Rock samples were collected from drill cores from various depths between 3600–4000 m.
