Calculation of the inverse relaxation time and the activation energy as a function of temperature for the Raman modes close to the phase transitions in solid nitrogen
(Elsevier, 2021)
The inverse relaxation time is calculated as a function of temperature for the transitions of alpha - beta (P = 0) and epsilon-delta(loc)-delta (at constant pressures) in the solid N-2. For this calculation, the observed ...
Liquid-(Solid plus Liquid) Transitions in a Two-Component System of (CH3)CCl3 + CCl4
(Springer/Plenum Publishers, 2020)
Liquid-(solid + liquid) transitions are studied in (CH3)CCl3 + CCl4 by using the Landau phenomelogical model. The Gibbs energy is expanded in terms of the orientational disorder (OD) parameters for the transitions of the ...
Three-parameter (3P) weibull distribution for characterization of strength of ceramics showing R-Curve behavior
(Elsevier Sci Ltd, 2021)
Strength distribution of advanced ceramics is commonly characterized by two-Parameter (2P) Weibull distribution. However, deviation of strength distribution from 2P-Weibull distribution may occur in ceramics due to various ...
