Rheology of biopolymer stabilized emulsions

open access: yesGrasas y Aceites, 1997
In this work, the viscous and viscoelastic responses of food emulsions stabilized by proteins are studied. The damping function determined from the relaxation modulus, together with the relaxation spectrum calculated from the dynamic modulus, allowed a ...

Influences of carbon nanotubes and graphite hybrid filler on properties of natural rubber nanocomposites

open access: yesPolymer Testing, 2021
Natural rubber (NR) vulcanizates reinforced by carbon nanotubes (CNT, 3 phr), graphite particles (GP) and CNT/GP hybrid filler (varied GP 0–50 phr) were prepared.

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Viscoelastic Finite Line Contact of Thin Bonded Layered Solids of Low Elastic Modulus

open access: yesApplied Sciences, 2020
A new finite element-based contact mechanics analysis of layered viscoelastic solids of low elastic modulus is presented. The methodology is based on the Maxwell viscoelastic element, with stress relaxation taken into account by the Prony series ...

The effect of age and initial compression on the force relaxation response of the femur in elderly women

open access: yesRoyal Society Open Science, 2022
The effect of force amount, age, body weight and bone mineral density (BMD) on the femur's force relaxation response was analysed for 12 donors (age: 56–91 years). BMD and fracture load, FL, were estimated from clinical CT images.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Frequency Dependent Rheology of Vesicular Rhyolite [PDF]

open access: yes, 1993
Frequency dependent rheology of magmas may result from the presence of inclusions (bubbles, crystals) in the melt and/or from viscoelastic behavior of the melt itself.

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Applying the fractional derivative Zener model to fitting the time-dependent material viscoelasticity tested by nanoindentation

open access: yesBiosurface and Biotribology, 2018
Material viscoelasticity is of particular importance for polymers, biotissues and many others, due to the significant influence not only on the elastic response of structures, but also on their failure mechanism in actual applications. In this study, the
