Oscillatory Normal Stresses in Dilute Polymer Solutions

The Journal of Chemical Physics, 1969
The Rouse–Zimm theories of polymer solution dynamics have been extended to include normal stresses as well as shear stresses and have been evaluated for low-amplitude oscillatory shear. Two normal stress coefficients (ζd, characterizing a displacement function, and ζ*, characterizing the oscillation about the displacement) appear as analogs to the ...

Non-Newtonian oscillatory layer flow, approximate solution

Collection of Czechoslovak Chemical Communications, 1979
The problem of the oscillatory flow of pseudoplastic liquid in vicinity of the infinitely long horizontal plane is formulated in stresses. For Re i.e. for conditions of oscillatory boundary layer the problem is solved approximately by the Galerkin method.

Non-conservative oscillatory systems with periodic solutions

International Journal of Non-Linear Mechanics, 1981
Abstract This note extends the work of previous authors to the closed orbits of non-linear oscillatory systems. The simple phase plane analysis is used.

Improved numerical solutions of nonlinear oscillatory systems

International Journal for Numerical Methods in Engineering, 2019
SUMMARYWe consider numerical solutions of nonlinear oscillatory systems where closed‐form solutions do not exist. Such systems occur in buckling of columns, electrical oscillations of circuits containing inductance with an iron core, and vibration of mechanical systems with nonlinear restoring forces. We have improved the accuracy, stability, and speed

Oscillatory solutions of some integrable differential equations

Monatshefte für Mathematik, 2010
In some cases, the analysis of a class of reaction-diffusion equations of the form \[ \Delta u+a\left( x,u\right) +b\left( \left| x\right| \right) x\cdot\nabla u=0,\qquad\left| x\right| >0,\;n\geq3, \] reduces to the study of the asymptotic behavior of solutions to the nonlinear differential equation \[ y^{\prime\prime}+p\left( t\right) \left( y ...

Oscillatory properties of solutions of the equations

Applicable Analysis, 1996
We study the oscillation and nonoscillat,ion of solutions of the two equations Also, for the (-) equation conditions for the faster-than-exponential growth and decay of solutions are obtained. Properties of the characteristic equations are used.
