Viscoelastic Parameters from Dielectric Relaxation Studies
Japanese Journal of Applied Physics, 1973Dielectric constant and loss are measured at 4.0 GHz for dilut solutions of two substituted ethanes (viz. 1.1-Dichloro-1-Nitroethane and 1,1,2,2-Tetrabromoethane) over a wide range of viscosity using benzene+nujol as a solvent and at the temperatures of 35, 45, 55 and 65°C.

Viscoelastic relaxation in amorphous bulk polymers
2007We report ultrasonic relaxation measurements of amorphous bulk polybutadiene (\( \bar M_w = 13000 \) , T g =222 K) and poly(phenyl methyl siloxane) (\( \bar M = 5000 \) , T g =235 K) in the temperature range 280 K–360 K and frequency range 0.1–100 MHz. Complementary polarized photon correlation studies were performed on the same polybutadine sample.

Low-Frequency Viscoelastic Relaxation in Liquids
Russian Physics Journal, 2014Results of experimental investigation of the low-frequency shear elasticity of liquids depending on the angle of shear strain are presented. A cluster model of the liquid structure is suggested to explain the low-frequency viscoelastic relaxation.

Relaxation in elastic and viscoelastic materials
Journal of Materials Science, 1984The mechanical compliance and modulus retardation/relaxation functions are examined in terms of a general behaviour which contains more than one process. An analytical approach to the transformation in the anelastic response between the compliance and the modulus is derived and applied to a cooperative model of relaxation behaviour. In particular it is

Viscoelastic relaxation of Enceladus’s ice shell
Icarus, 2017Abstract We propose a dynamic model relating the non-hydrostatic long-wavelength topography on Enceladus to loading at the base of the ice shell. In dynamic equilibrium, the surface topography induced by a bottom load is very close to that inferred for Airy isostasy.

Viscoelastic relaxation of supercooled liquids. II
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1967In addition to the six liquids for which the results of viscoelastic measurements are reported in part I, studies have also been made on a further eight liquids which differ widely in molecular composition, namely: squalane, tri( β -chloroethyl) phosphate, tri( o -tolyl) phosphate, tri(

Viscoelastic relaxation of supercooled liquids. I
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1967Complete information is presented for the viscoeleastic behaviour ofn-propyl benzene, isopropyl benzene,sec. -butyl benzene, di(n-butyl) phthalate. di(isobutyl) phthalate and di(2-ethyl hexyl) phthalate. These liquids have been measured in the supercooled state using alternating shear stress of frequencyf( =ω/2π), from the purely viscous range, through
