WebNov 15, 2024 · B 1 = C 1 C 2 B 2 = C 2 − T r. Everytime RepTate calculates or fits the theory to a set of experimental data, it will output the values of the standard WLF parameters C 1 and C 2 at the temperature T r in the theory window. In the vertical shift, the modulus is modified according to the expression: G ( T r) = b T G ( T) WebTypically used to determine the temperature dependence of the viscosity or the shift factors (TTS). Comments In the region between Tg and (Tg+100°C), use of the WLF model. (The TRIOS Arrhenius model is designed to fit data that have been shifted using TTS).

WebIn the case of WLF behaviour the shift factor is given by 1 : -C°(T - To) log(at) = (2) C O + (T- To) where the coefficients C o and C o are related to the free volume at To and to the free-volume coefficient of thermal expansion.

WebTime-temperature superposition – TTS (WLF, Arrhenius, numeric – optional) Evaluation of Complex Modulus The complex modulus consists of two components, the storage and the loss moduli. The storage modulus (or Young’s modulus) describes the stiffness and the loss modulus describes the damping (or viscoelastic) behavior of the corresponding sample … http://www.ifug.ugto.mx/~labblanda/manuales/Content/Rheology%20Common%20Topics/Analysis%20Models/Arrhenius.htm devens disc golf the hill
