Relaxation function for the non-Debye relaxation spectra description

Chemical Physics, 2014
Abstract This study presents the new relaxation function describing the non-Debye relaxation phenomena. The relaxation function is based on a new theoretical model of the relaxation polarization. The non-Debye relaxation is explained with the model of nonlinear damped oscillator.

Stress relaxation function of glass

Solid State Communications, 1971
It has been found by Douglas and others that the stress relaxation function of glass has the form S = S0 exp[ -(t/τ)α]. Simple phenomenological considerations, utilizing the theory of Brownian motion, can explain this law and yield proper values of α and τ.

Tractable Relaxations of Composite Functions

Mathematics of Operations Research, 2022
In this paper, we introduce new relaxations for the hypograph of composite functions assuming that the outer function is supermodular and concave extendable. Relying on a recently introduced relaxation framework, we devise a separation algorithm for the graph of the outer function over P, where P is a special polytope to capture the structure of each ...

Relaxation time distribution function

Ferroelectrics, 2000
Abstract The distribution function of relaxation time in disordered dielectrics has been calculated in the random field theory framework. For this purpose, we first consider the dynamics of single two-orientable electric dipole in a random electric field E in a disordered ferroelectric.
