Hi,
I am simulating the blow-moulding process based on injection using ANSYS Workbench Polyflow Module.
I am doing a viscoelastic isothermal analysis, and I am using the KBK-Z model for viscoelasticity. The inputs are Viscosity and respective relaxation time.
I know that temperature does not exist on this analysis. However, I would like to estimate the temperature at which PET has this spectrum shown next:
Mode Viscosity (Pa-s) Relaxation time (s)
1 1E+04 0.01
2 3E+04 0.1
3 1E+05 1
Or, even better, how can I calculate it? There is any way?
Best regards,
AndradeLopes
