The model for flow-induced crystallization suggested here involves a long series of material parameters. They are currently available for a limited range of materials, while protocol measurements and techniques for parameter identifications still have to be developed.
The FIC model actually involves the evaluation of three tensors: ,
, and an auxiliary tensor for
. This can be computationally expensive, especially for 3D flows.
Hence the present crystallization model is available in single-mode only. The use of
a modified Giesekus model with finite chain extensibility is endowed with realistic
rheological properties, such as shear thinning and normal stress differences.
