A class of solitons in Maxwell-scalar and Einstein–Maxwell-scalar models [PDF]

open access: yesThe European Physical Journal C, 2020
AbstractRecently, no-go theorems for the existence of solitonic solutions in Einstein–Maxwell-scalar (EMS) models have been established (Herdeiro and Oliveira in Class Quantum Gravity 36(10):105015, 2019). Here we discuss how these theorems can be circumvented by a specific class of non-minimal coupling functions between a real, canonical scalar field ...

Linear viscoelasticity of liquid crystalline phases for a ethoxylated nonylphenol nonionic surfactant/water system

open access: yesGrasas y Aceites, 2002
In this work the linear viscoelastic behaviour of micelar and liquid-crystalline phases in a polyoxy-ethylene glycol nonylphenyl ether (EOa=10)/water system was studied.

Mathematical Models Describing the Creep and Stress Relaxation Behavior of False Banana’s Fiber (Ensete Ventricosum)

open access: yesJournal of Natural Fibers, 2021
Viscoelastic behavior is an important parameter for the use of natural fibers in technical applications. Mathematical models to describe the relaxation and creep behavior of Ensete fibers were investigated.

Rheology of Linear Viscoelastic Materials [PDF]

open access: yesWarasan Witthayasat Lae Theknoloyi Mahawitthayalai Mahasarakham, 2020
This article shows the relationship between stress and strain of a generalized linear viscoelastic material. From a well-known Maxwell constitute equation, a model that contains a spring and a dashpot connected in series, a linear viscoelastic model is ...

Using a Fully Fractional Generalised Maxwell Model for Describing the Time Dependent Sinusoidal Creep of a Dielectric Elastomer Actuator

open access: yesFractal and Fractional, 2022
Actuators made of dielectric elastomers are used in soft robotics for a variety of applications. However, due to their mechanical properties, they exhibit viscoelastic behaviour, especially in the initial phase of their performance, which can be observed

Tanaka Theorem for Inelastic Maxwell Models [PDF]

open access: yesCommunications in Mathematical Physics, 2007
We show that the Euclidean Wasserstein distance is contractive for inelastic homogeneous Boltzmann kinetic equations in the Maxwellian approximation and its associated Kac-like caricature. This property is as a generalization of the Tanaka theorem to inelastic interactions. Consequences are drawn on the asymptotic behavior of solutions in terms only of

A viscoelastic flow model of Maxwell-type with a symmetric-hyperbolic formulation

open access: yesComptes Rendus. Mécanique, 2023
Maxwell models for viscoelastic flows are famous for their potential to unify elastic motions of solids with viscous motions of liquids in the continuum mechanics perspective.
