Relationship between rheology and structure of interpenetrating, deforming and compressing microgels
Nature Communications, 2019 Thermosensitive microgels are widely studied polymer-colloid hybrids but their interactions and packing are still not fully understood. Here, the authors study the linear viscoelasticity of dense microgels and analyse the local particle structure and ...

Vibrations modeled by the standard linear model of viscoelasticity with boundary dissipation
Electronic Journal of Differential Equations, 2017 We consider vibrations modeled by the standard linear solid model of viscoelasticity with boundary dissipation. We establish the well-posedness and the exponential stability.

A generalization of the Lomnitz logarithmic creep law via Hadamard fractional calculus
, 2017 We present a new approach based on linear integro-differential operators with logarithmic kernel related to the Hadamard fractional calculus in order to generalize, by a parameter $\nu \in (0,1]$, the logarithmic creep law known in rheology as Lomnitz ...

Fluidification of entangled polymers by loop extrusion
Physical Review ResearchLoop extrusion is one of the main processes shaping chromosome organization across the cell cycle, yet its role in regulating deoxyribonucleic acid (DNA) entanglement and nucleoplasm viscoelasticity remains overlooked.

Бюллетень Почвенного института им. В.В. Докучаева, 2017 The rheological properties of two profile`s horizons of soddy-podzolic and agro soddy-podzolic soil were studied by the amplitude sweep test on a rheometer MCR-302 (Anton Paar, Austria) on samples of natural structure (pastes) and disturbed structure ...

A class of linear viscoelastic models based on Bessel functions
, 2016 In this paper we investigate a general class of linear viscoelastic models whose creep and relaxation memory functions are expressed in Laplace domain by suitable ratios of modified Bessel functions of contiguous order. In time domain these functions are

Calculation of high-frequency dynamic properties of squeezed O-ring for bearing support
Mechanical Engineering Journal, 2018 Determination and prediction of the dynamic properties of an O-ring for bearing support were performed. Utilizing O-rings as supporters of bearing is a promising way to suppress severe vibrations such as resonance and self-excited whirl experienced in ...

Distributed order fractional constitutive stress-strain relation in wave propagation modeling
, 2018 Distributed order fractional model of viscoelastic body is used in order to describe wave propagation in infinite media. Existence and uniqueness of fundamental solution to the generalized Cauchy problem, corresponding to fractional wave equation, is ...

Lattice Boltzmann simulations of a viscoelastic shear-thinning fluid
, 2015 We present a hybrid lattice Boltzmann algorithm for the simulation of flow glass-forming fluids, characterized by slow structural relaxation, at the level of the Navier-Stokes equation. The fluid is described in terms of a nonlinear integral constitutive
