Abstract

The study developed an experimental-computational procedure for investigating the rheological properties of thermoplastic slip. This approach integrates laboratory and computational experiments conducted in parallel to determine viscosity parameters by ensuring agreement between calculated and experimental data. The experimental component employs penetrometry, a method that is simple to implement and does not require specialized equipment. The computational component involves analyzing a model boundary-value problem for the Navier–Stokes equations using the finite element method or applying the analytical model developed in this work. The viscosity characteristics of slip based on paraffin and polydisperse SiC powder enable the prediction of the slip-casting process for large-scale, thin-walled silicon carbide ceramic components.
