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.

Rheological Properties of Polyurethane-Based Magnetorheological Gels

open access: yesFrontiers in Materials, 2019
The paper tests the influence of mass fractions of carbonyl iron particles (CIPs) on the rheological properties of magnetorheological (MR) gels. Polyurethane-based MR gels with different weight fraction of CIPs, i.e., 40, 60, and 80%, were firstly ...

Phase-inherent linear visco-elasticity model for infinitesimal deformations in the multiphase-field context

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2020
A linear visco-elasticity ansatz for the multiphase-field method is introduced in the form of a Maxwell-Wiechert model. The implementation follows the idea of solving the mechanical jump conditions in the diffuse interface regions, hence the continuous ...

Investigation of the Viscoelastic Effect on Optical- Fiber Sensing and Its Solution for 3D-Printed Sensor Packages [PDF]

open access: yes, 2019
Viscoelasticity is an effect seen in a wide range of materials and it affects the reliability of static measurements made using Fiber Bragg Grating-based sensors, because either the target structure, the adhesive used, or the fiber ...

Some Methods of Solving Problems of Non-Linear Thermo-Viscoelasticity

open access: yesEngineering Transactions, 1974
The formulation of the problems of non-linear thermo-viscoelasticity, including also coupled problems is given. For that purpose application of thermodynamics of irreversible processes to the visco-elastic media is analysed.

Development of Creep Deformations during Service Life: A Comparison of CLT and TCC Floor Constructions

open access: yesBuildings, 2022
Cross-laminated timber (CLT) slabs in residential buildings need additional weight, e.g., in the form of screeds or gravel layers, to fulfill the criterion for the highest impact-sound class.

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 $\nu=1$.

Diffusion and wave behaviour in linear Voigt model [PDF]

open access: yes, 2002
A boundary value problem related to a third- order parabolic equation with a small parameter is analized. This equation models the one-dimensional evolution of many dissipative media as viscoelastic fluids or solids, viscous gases, superconducting ...

Effect of Visco-Elasticity of an Orthotropic Arterial Wall on Pulse-Wave Propagation

open access: yesМеханика машин, механизмов и материалов, 2008
The problem of harmonic pressure wave propagation through a viscous fluid contained in a thin viscoelastic orthotropic tube is considered. To take into account viscoelasticity of the tube the linear viscoelasticity model is used.
