What is it about?
Polycarbonate squeeze flow combines both shear and extension characteristics, and exhibits nonlinear some properties. It is necessary to investigate its rheological characteristics so as to describe squeeze flow accurately.

Why is it important?
To avoid the difficult of measuring the inner melt rheological behavior directly, we presents a method to meaure the compressing force applied on the upper disc instead. Then explore the relationship between the force and polycarbonate rheology through solving the governing equations and constitutive equations by finite difference method.
