Analysis of creep curves produced by the linear viscoelasticity theory under cyclic stepwise loadings

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
Basic qualitative properties of the creep curves generated by the linear integral constitutive relation of viscoelasticity (with an arbitrary creep compliance) under cyclic piecewise-constant uni-axial loadings (with an arbitrary asymmetry stress ratio ...

Controllability of a viscoelastic plate using one boundary control in displacement or bending

open access: yes, 2016
In this paper we consider a viscoelastic plate (linear viscoelasticity of the Maxwell-Boltzmann type) and we compare its controllability properties with the (known) controllability of a purely elastic plate (the control acts on the boundary displacement ...

Brittle fracture of polymer transient networks [PDF]

open access: yes, 2017
We study the fracture of reversible double transient networks, constituted of water suspensions of entangled surfactant wormlike micelles reversibly linked by various amounts of telechelic polymers.

Linear viscoelasticity of the lamellar liquid crystalline phase for a heptane/nonionic surfactant/water system

open access: yesGrasas y Aceites, 2000
A linear viscoelastic characterization by small amplitude oscillatory shear tests was carried out for heptane/polyoxyethylene glycol nonylphenyl ether (EOa=10)/water system exhibiting a lamellar liquid crystalline structure.

Power law viscoelasticity of a fractal colloidal gel

open access: yes, 2018
Power law rheology is of widespread occurrence in complex materials that are characterized by the presence of a very broad range of microstructural length and time scales.

Linear Viscoelastic Responses: The Prony Decomposition Naturally Leads Into the Caputo-Fabrizio Fractional Operator

open access: yesFrontiers in Physics, 2018
The study addresses the physical background and modeling of linear viscoelastic response functions and their reasonable relationships to the Caputo-Fabrizio fractional operator via the Prony (Dirichlet series) series decomposition.

Length dependence of viscoelasticity of entangled-DNA solution with and without external stress

open access: yesAIP Advances, 2018
We observed the diffusive motion of a micron-sized bead in an entangled-DNA solution to investigate the effect of the viscoelasticity on the bead motion.

A Lattice Boltzmann study of the effects of viscoelasticity on droplet formation in microfluidic cross-junctions

open access: yes, 2016
Based on mesoscale lattice Boltzmann (LB) numerical simulations, we investigate the effects of viscoelasticity on the break-up of liquid threads in microfluidic cross-junctions, where droplets are formed by focusing a liquid thread of a dispersed (d ...

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

open access: yes, 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 $\nu=1$.

Stability and free energies in linear visco-elasticity

open access: yesLe Matematiche, 2007
Dedicated to the memory of Gaetano FicheraIn this paper we show that several free energies can be related to a material with fading memory with different domains of definition and topologies.
