A Theoretical Basis for the Application of Fractional Calculus to Viscoelasticity

, 1983
This article establishes a link between molecular theories that predict the macroscopic behavior of certain viscoelastic media and an empirically developed fractional calculus approach to viscoelasticity.

Dynamics of Polymer Molecules in Dilute Solution: Viscoelasticity, Flow Birefringence and Dielectric Loss

, 1956
The problem of the motions of a chain molecule diffusing in a viscous fluid under the influence of external forces or currents is considered for a particular model. This model is a chain of beads connected by ideal springs.

Swelling of viscoelastic matrices by viscoelastic fluids

2018
A typical example of viscoelastic matrices is represented by polymeric particles devoted to the controlled release of active agents (drugs) that swell when put in contact with an external solvent, typically a physiological medium. Although, in general, physiological fluids can be considered Newtonian, this is not always the case, let us consider, for ...

On infinite order differential operators in fractional viscoelasticity

, 2017
In this paper we discuss some general properties of viscoelastic models defined in terms of constitutive equations involving infinitely many derivatives (of integer and fractional order).

Droplet formation in a flow focusing configuration: Effects of viscoelasticity

, 2016
We numerically investigate the effects of bulk fluid viscoelasticity on droplet formation and dynamics in an axisymmetric flow focusing configuration. Viscoelasticity is modeled using the finitely extensible nonlinear elastic-Chilcott-Rallison (FENE-CR ...

Viscoelasticity and Thermoviscoelasticity

2017
This chapter presents an overview of the development of the three-dimensional theories of viscoelasticity and thermoviscoelasticity. An understanding of these models is essential to the ability to predict the response of flexible pavements containing asphalt binder, as well as rate-dependent base materials.

Experiments on Viscoelasticity

American Journal of Physics, 1956
The propagation of sound waves in rubber strips is used to illustrate visco-elastic behavior. The experiments introduce time-dependent mechanical properties of solids at a level suitable for use in undergraduate laboratories.
