Bubble dynamics in polymeric foams [PDF]
The effects of fluid viscoelasticity on the expansion of gas bubbles in polymer foams for both non-reactive and reactive polymers are investigated. Polymer foams are used extensively in consumer products, from car parts to upholstery.

Computational modelling of some problems of elasticity and viscoelasticity with applications to thermoforming process [PDF]
Copyright @ 2012 Northwestern Polytechnical University and ISCIThe reliability of computational models of physical processes has received much attention and involves issues such as the validity of the mathematical models being used, the error in any ...

An approach to nonlinear viscoelasticity via metric gradient flows [PDF]
We formulate quasistatic nonlinear finite-strain viscoelasticity of rate type as a gradient system. Our focus is on nonlinear dissipation functionals and distances that are related to metrics on weak diffeomorphisms and that ensure time-dependent frame ...

The mobility of sustained molecules is influenced by viscoelasticity, which is strongly correlated with the diffusional property in polymeric liquid. However, the study of transient networks formed by a reversible crosslink, which is the viscoelastic ...

Viscoelasticity of the extracellular matrix (ECM) plays a critical part in controlling cell behavior. However, the structure-related viscoelasticity of the synthetic ECM and its mechanism are rarely reported.

Influence of supramolecular forces on the linear viscoelasticity of gluten [PDF]
Stress relaxation behavior of hydrated gluten networks was investigated by means of rheometry combined with μ-computed tomography (μ-CT) imaging. Stress relaxation behavior was followed over a wide temperature range (0–70 °C).

Photoacoustic viscoelasticity imaging dedicated to mechanical characterization of biological tissues [PDF]
Since changes in mechanical properties of biological tissues are often closely related to pathology, the viscoelastic properties are important physical parameters for medical diagnosis.

Relative entropy in diffusive relaxation [PDF]
We establish convergence in the diffusive limit from entropy weak solutions of the equations of compressible gas dynamics with friction to the porous media equation away from vacuum.

Viscoelastic properties of crystals [PDF]
We examine the question of whether fluids and crystals are differentiated on the basis of their zero frequency shear moduli or their limiting zero frequency shear viscosity. We show that while fluids, in contrast with crystals, do have a zero value for their shear modulus, in contradiction to a widespread presumption, a crystal does not have an ...
