Mathematical analysis of thermo-visco-elastic models
Motywacją do badań nad równaniami opisującymi odkształcenia termo-lepko-sprężyste jest potrzeba lepszego opisu procesów zachodzących w różnych materiałach oraz zbudowania lepszych modeli ich zachowania pod wpływem działania sił zewnętrznych. Wraz z rozwojem techniki zdobywamy głębszą wiedzę na temat różnych tworzyw. Pozwala nam to na tworzenie coraz bardziej poprawnych modeli opisujących zachow...
متن کاملHomogenization of nonlinear visco-elastic composites
Quasi-static processes in nonlinear visco-elastic materials of solid-type are here represented by the system: σ −B(x) : ∂ε ∂t ∈ β(ε, x), −divσ = f , (∗) coupled with initial and boundary conditions. Here σ denotes the stress tensor, ε the linearized strain tensor, B(x) the viscosity tensor, β(·, x) a (possibly multi-valued) maximal monotone mapping, and f an applied load. Existence and uniquene...
متن کامل2 A Computational Model for Visco - Elastic
Particle diiusion in rotating drums is studied via computer simulations using a full 3-D model which does not involve any arbitrary input parameters. The diiusion coeecient for single-component systems agree qualitatively with previous experimental results. On the other hand, the diiusion coeecient for two-component systems is shown to be a highly nonlinear function of the rotation velocity. It...
متن کاملVisco-elastic Spectra of a Dilute Bose Fluid
A recently developed local-density current functional formalism for confined Bose-condensed superfluids requires visco-elastic spectra which are defined through a finite-frequency extension of the dissipative coefficients entering the linearized hydrodynamic equations of the two-fluid model. We evaluate these spectra for a superfluid with contact interactions in the collisionless regime at fini...
متن کاملDynamic Analysis of Axially Beam on Visco - Elastic Foundation with Elastic Supports under Moving Load
For dynamic analyses of railway track structures, the algorithm of solution is very important. For estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. For studying the effects of axially beam on the ela...
