The dielectric modulus: relaxation versus retardation

Solid State Ionics, 1998
Abstract Experiments which access the quantity e*(ω) are usually termed dielectric relaxation methods, although e*(ω) and e(t) actually refer to dielectric retardation. The true dielectric relaxation, the modulus M(t), corresponds to the decay of the electric field under the conditions of a constant dielectric displacement.

MODULUS AND RELAXATION OF ELASTOMERS IN TORSION AT LOW TEMPERATURES

Industrial & Engineering Chemistry, 1952
Abstract Second-order transition temperatures, Ts, indicated by volume or specific heat data, have been reported for many high polymer elastomers. Studies of the modulus-temperature relationship in the vicinity of Ts have revealed that the modulus below Ts is always enormously higher than above Ts. In the transition region, roughly from Ts+10°C

Stress Relaxation Modulus of a Commercial Glass

Journal of the American Ceramic Society, 1973
The stress relaxation modulus in compression of a container glass was investigated over a wide range of strain, time, modulus, and temperature. The glass is a linear viscoelastic liquid up to 2% strain, and the modulus is a smooth function of time, with no pseudorubbery plateau apparent down to a modulus of 10° dynes/cm

Simultaneously obtaining the Young's relaxation modulus and shear relaxation modulus of an epoxy molding compound by using DMA

2014 IEEE 16th Electronics Packaging Technology Conference (EPTC), 2014
In this work, a methodology is developed for obtaining the Young's relaxation modulus and shear relaxation modulus simultaneously by using a single dynamic mechanical analysis (DMA) experiment. The bulk modulus is assumed as a constant and calculated by Poisson's ratio.

Similarity of the relaxation modulus of polydisperse polymers

Makromolekulare Chemie. Macromolecular Symposia, 1993
AbstractA similarity rule due to Markovitz is used for the correlation of the relaxation modulus for different polymeric materials. This rule has long been employed implicitly in the empirical shifting rules for the reduction to common curves of viscoelastic data measured on the same polymer over a range of temperatures and concentrations.
