Contribution to studying the structural analysis of rocket fuel

Vojnotehnički Glasnik, 1995
A brief review of possible stresses and deformation of rocket fuel while stored, in its preparation for exploitation and in the course of exploitation. The procedure of its structural analysis is described and shortcomings of the calculation based on the

Rouse Chains with Excluded Volume Interactions: Linear Viscoelasticity

, 2000
Linear viscoelastic properties for a dilute polymer solution are predicted by modeling the solution as a suspension of non-interacting bead-spring chains.

Identification of the relaxation kernel in diffusion processes and viscoelasticity with memory via deconvolution

, 2016
We present an algorithm for the identification of the relaxation kernel in the theory of diffusion systems with memory (or of viscoelasticity) which is linear, in the sense that we propose a linear Volterra integral equation of convolution type whose ...

Dynamic viscoelasticity of commercial mayonnaise: influence of temperature and oil content

Grasas y Aceites, 1991
The linear dynamic viscoelasticity of two commercial foodstuffs, oil in water emulsions with very different oil contents, has been studied. Temperature ranged between 10 and 40°C.

Nonlinear viscoelasticity of metastable complex fluids

, 2006
Many metastable complex fluids such as colloidal glasses and gels show distinct nonlinear viscoelasticity with increasing oscillatory-strain amplitude; the storage modulus decreases monotonically as the strain amplitude increases whereas the loss modulus

Deformation and break-up of viscoelastic droplets in confined shear flow [PDF]

, 2016
The deformation and break-up of Newtonian/viscoelastic droplets are studied in confined shear flow. Our numerical approach is based on a combination of Lattice-Boltzmann models (LBM) and finite difference schemes, the former used to model two immiscible ...

A 3-dimensional singular kernel problem in viscoelasticity: an existence result

, 2018
Materials with memory, namely those materials whose mechanical and/or thermodynamical behaviour depends on time not only via the present time, but also through its past history, are considered.

On nonlinear viscoelastic deformations - a reappraisal of Fung's quasilinear viscoelastic model [PDF]

, 2014
This article offers a reappraisal of Fung's method for quasilinear viscoelasticity. It is shown that a number of negative features exhibited in other works, commonly attributed to the Fung approach, are merely a consequence of the way it has been applied.

Modeling of the study of viscoelastic deformation of elastic bodies

Современная математика: Фундаментальные направления
This article proposes a numerical-analytical method for solving linear viscoelasticity problems of an anisotropic solid without the need for explicit analytical representations of creep and relaxation kernels.
