On thermodynamics of incompressible viscoelastic rate type fluids with temperature dependent material coefficients

J Hron, V Miloš, V Průša, O Souček, K Tůma - International Journal of Non …, 2017 - Elsevier
We derive a class of thermodynamically consistent variants of Maxwell/Oldroyd-B type
models for incompressible viscoelastic fluids. In particular, we study the models that allow …

Infinitesimal and infinite numbers in applied mathematics

A Bryzgalov, K Islami, P Giordano - Nonlinear Dynamics, 2024 - Springer
The need to describe abrupt changes or response of nonlinear systems to impulsive stimuli
is ubiquitous in applications. Also the informal use of infinitesimal and infinite quantities is …

On the pitfalls of diffuse interface methods in problems involving non-material interfaces

P Kottman, O Souček - International Journal of Non-Linear Mechanics, 2024 - Elsevier
In this paper, we discuss the implications of applying traditional diffuse-interface techniques
to problems involving mass flux across the interface such as the phase change front. In a …

Viscoelastic rate type fluids with temperature dependent material parameters--stability of the rest state

J Stein, V Průša - arXiv preprint arXiv:1701.08966, 2017 - arxiv.org
We study the dynamics of small perturbations to the rest state of a viscoelastic rate type fluid
with temperature dependent material parameters. We show that if the material parameters …

On the response of nonlinear viscoelastic materials in creep and stress relaxation experiments in the lubricated squeeze flow setting

M Řehoř, V Průša, K Tůma - Physics of Fluids, 2016 - pubs.aip.org
Rigorous analysis of the response of nonlinear materials to step inputs requires one to
simultaneously handle the discontinuity, differentiation, and nonlinearity. This task is …

[HTML][HTML] A comparison of constitutive models for describing the flow of uncured styrene-butadiene rubber

M Řehoř, A Gansen, C Sill, P Polińska… - Journal of Non …, 2020 - Elsevier
Uncured styrene-butadiene rubber (SBR) can be modelled as a viscoelastic material with at
least two different relaxation mechanisms. In this paper we compare multi-mode constitutive …

A note on parametric resonance induced by a singular parameter modulation

D Pražák, V Průša, K Tůma - International Journal of Non-Linear …, 2022 - Elsevier
We investigate the classical problem of motion of a mathematical pendulum with an
oscillating pivot. This simple mechanical setting is frequently used as the prime example of a …

LL Baglini, P Giordano, D Kebiche, H Vernaeve - Preprint, 2019 - mat.univie.ac.at
After the presentation in [20] of the basic theory of generalized smooth functions (GSF), in
the present paper, we deal with Cauchy problems for ODE in the so-called normal form, ie {y …

[PDF][PDF] CONSTITUTIVE RELATIONS AND MAXIMUM RATE OF ENTROPY PRODUCTION IN NON-EQUILIBRIUM PROCESSES

V Pruša - jetc2017.hu
The critical step in the formulation of complete set of governing equations for motion of
continuous medium is the mathematical description of the behaviour of the specific material …
