Consolidation of Viscoelastic Soil With Vertical Drains for Continuous Drainage Boundary Conditions Incorporating a Fractional Derivative Model

open access: yesFrontiers in Materials, 2021
In geotechnical engineering, vertical drainage is the most economical method for accelerating the consolidation of a large area of soft ground. In this study, we analyze the viscoelasticity of the soil and the actual drainage conditions on the top ...

Some remarks on the model of rigid heat conductor with memory: unbounded heat relaxation function [PDF]

open access: yes, 2019
The model of rigid linear heat conductor with memory is reconsidered focussing the interest on the heat relaxation function. Thus, the definitions of heat flux and thermal work are revised to understand where changes are required when the heat flux ...

The relationship between viscoelasticity and elasticity [PDF]

open access: yesProceedings of the Royal Society A, 2019
Soft materials that are subjected to large deformations exhibit an extremely rich phenomenology, with properties lying in between those of simple fluids and those of elastic solids.

A Lattice Boltzmann study of the effects of viscoelasticity on droplet formation in microfluidic cross-junctions

open access: yes, 2016
Based on mesoscale lattice Boltzmann (LB) numerical simulations, we investigate the effects of viscoelasticity on the break-up of liquid threads in microfluidic cross-junctions, where droplets are formed by focusing a liquid thread of a dispersed (d ...

Traveling waves in one-dimensional nonlinear models of strain-limiting viscoelasticity [PDF]

open access: yes, 2015
In this article we investigate traveling wave solutions of a nonlinear differential equation describing the behaviour of one-dimensional viscoelastic medium with implicit constitutive relations.

Matrix viscoelasticity promotes liver cancer progression in the pre-cirrhotic liver

open access: yesNature
Type 2 diabetes mellitus is a major risk factor for hepatocellular carcinoma (HCC). Changes in extracellular matrix (ECM) mechanics contribute to cancer development1,2, and increased stiffness is known to promote HCC progression in cirrhotic conditions3 ...
