50 Years of the K-BKZ Constitutive Relation for Polymers
Figure 11
Bagley plot for two polyethylene melts. The effect of on the pressure at various values of apparent shear rate (all effects accounted for). Symbols are experimental data while lines are simulations with the K-BKZ/PSM model: (a) LDPE melt at 160°C [45], (b) HDPE melt at 190°C [46].
