 Once both components (A and B) have been selected or created, define the mixing ratio. This is usually done by entering the respective percentages or mass proportions of the two components.
-Click on //Define mixing ratio//. Enter the desired proportions of the components, e.g. 70 % polymer A and 30 % filler B.
+Enter the desired proportions of the components, e.g. 70 % polymer A and 30 % filler B.
+=====Step 6: Definition of viscosity=====
+The viscosity can be determined in several ways. Either the rheological data of the mixture can be specified directly or mixing rules can be used.
+Mixture rules for polymer-polymer mixtures (with component proportions $w_A$ and $w_B$):
+  * Logarithmic: $$log(\eta_M)=w_A log(\eta_A)+w_B log(\eta_B)$$
+  * Mantford's rule of mixtures: $$\eta_M^{\frac{1}{3,4}}=w_A \eta_A^{\frac{1}{3,4}}+w_B \eta_B^{\frac{1}{3,4}}$$
+  * Mixture rule according to Takayanagi (with continuous phase c, dispersed phase d and phase fraction of the dispersed phase of $\Phi_d$): $$\eta_M=\eta_c \cdot \frac{3 \eta_c + 2\eta_d - 3(\eta_c-\eta_d) \Phi_d}{3 \eta_c + 2\eta_d+2(\eta_c-\eta_d) \Phi_d}$$
+Mixture rules for polymer-filler mixture (with filler content $\Phi_F$):
+  * Einstein's mixing rule: $$\eta_M=\eta_p(1+2.5\Phi_F)$$
+  * Mixture rule according to Hashin: $$\eta_M=\eta_p(1+\frac{2 \Phi_F}{1-\Phi_F})$$
 =====Completion of the mixture creation=====
-Once the mixing ratio has been defined, save the mixture by clicking on //Save// or //Create mixture//. The newly created mixture can now be used for simulations, calculations or further processing in plastics technology.
+Once the mixing ratio has been defined, save the mixture by closing the window via the //Ok// Button. The newly created mixture can now be used.
