| + | There is only one option to calculate the viscosity of a gas-loaded polymer in SIGMA. So, the Carreau function is preselected for the viscosity function. | ||
| + | |||
| + | |||
| + | |||
| + | Carreau: | ||
| + | |||
| + | $n = \frac{A \cdot a_T \cdot a_{gas}}{(1 + B \cdot a_T \cdot a_{gas} \cdot \dot{\gamma})^C}$ | ||
| + | |||
| + | |||
| + | |||
| + | You can choose from different temperature dependence. | ||
| + | * WLF ($T_b, T_s$) | ||
| + | * WLF ($C_1, C_2$) | ||
| + | * Arrhenius | ||
| + | |||
| + | |||
| + | |||
| + | |||
| + | These different models for the temperature shift factor a_T are described in detail in subchapter rheological data. | ||
