A continuum and computational framework for viscoelastodynamics: I. Finite deformation linear models

Liu, Ju; Latorre, Marcos; Marsden, Alison L. (Elsevier, 2021-11-01)

[EN] This work concerns the continuum basis and numerical formulation for deformable materials with viscous dissipative mechanisms. We derive a viscohyperelastic modeling framework based on fundamental thermomechanical ...
Anisotropic finite strain viscoelasticity based on the Sidoroff multiplicative decomposition and logarithmic strains

Latorre, Marcos; Montáns, Francisco Javier (Springer-Verlag, 2015-08-02)

[EN] In this paper a purely phenomenological formulation and finite element numerical implementation for quasi-incompressible transversely isotropic and orthotropic materials is presented. The stored energy is composed of ...
Behaviour of free falling viscoelastic liquid jets

Tirel, Christophe; Renoult, Marie-Charlotte; Dumouchel, Christophe; Blaisot, Jean-Bernard (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] In a recent work, a protocol to measure the relaxation time of dilute polymer solutions, known to be challenging, has been established [1]. This protocol is based on a 2D multi-scale description of free-falling low ...

[ES] En este TFM se estudiarán las propiedades mecánicas de materiales viscoelásticos a partir del análisis de la dinámica de una esfera rígida situada en interior del material. Para ello se utilizará y controlará un sistema ...
Characterization of Viscoelastic Media Combining Ultrasound and Magnetic-Force Induced Vibrations on an Embedded Soft Magnetic Sphere

Cebrecos, Alejandro; Jimenez, Noe; Tarazona Tárrega, Rafael; Company, Miguel; Benlloch Baviera, Jose María; Camarena Femenia, Francisco (Institute of Electrical and Electronics Engineers, 2021-12)

[EN] We report a method to locally assess the complex shear modulus of a viscoelastic medium. The proposed approach is based on the application of a magnetic force to a millimeter-sized steel sphere embedded in the medium ...
Chemical composition and temperature influence on the rheological behaviour of honeys

Oroian, Mircea Adrian; Amariei, Sonia; Escriche Roberto, Mª Isabel; Leahu, Ana; Damian, Cristina; Gutt, Gheorghe (Taylor & Francis (Routledge): STM, Behavioural Science and Public Health Titles, 2014)

The purpose of this work was to examine the viscoelastic properties of Spanish honeys with various sugar contents [fructose (32 42 g/100 g honey), glucose (24 35 g/100 g honey), sucrose (0.0 3.4 g/100 g honey)]; ...
Closed-form eigensolutions of nonviscously, nonproportionally damped systems based on continuous damping sensitivity

Lázaro, Mario (Elsevier, 2018)

[EN] In this paper, nonviscous, nonproportional, vibrating structures are considered. Nonviscously damped systems are characterized by dissipative mechanisms which depend on the history of the response velocities via ...
Critical roles of time-scales in soft tissue growth and remodeling

Latorre, Marcos; Humphrey, Jay D. (AIP Publishing, 2018-06-05)

[EN] Most soft biological tissues exhibit a remarkable ability to adapt to sustained changes in mechanical loads. These macroscale adaptations, resulting from mechanobiological cellular responses, are important determinants ...
Desarrollo de un sistema mixto magnético-ultrasónico para la caracterización de medios viscoelásticos

Company Arnalte, Miguel (Universitat Politècnica de València, 2018-04-16)

El presente TFM se enmarca en el área de caracterización de medios viscoelásticos para aplicaciones médicas, como la imagen elastográfica de tejidos biológicos, o aplicaciones industriales, como el control de calidad de ...
Formulación y caracterización de las propiedades reológicas y digestivas de una crema de champiñones enriquecida en proteína y con textura modificada

Benzama, Kaouther (Universitat Politècnica de València, 2021-10-06)

[ES] En el presente trabajo se evaluaron las propiedades reológicas, viscoelásticas y la digestibilidad proteica de una crema de champiñones enriquecida con proteína y con textura modificada. La crema fue enriquecida con ...
Fully anisotropic finite strain viscoelasticity based on a reverse multiplicative decomposition and logarithmic strains

Latorre, Marcos; Montáns, Francisco Javier (Elsevier, 2016-01-15)

[EN] In this paper we present a novel formulation for phenomenological anisotropic finite visco-hyperelasticity. The formulation is based on a multiplicative decomposition of the equilibrated deformation gradient into ...
