Viscous pull force evaluation in the pultrusion process by a finite element thermo-chemical rheological model

This paper deals with the development of computational model to investigate aconventionalpultrusion process. The model takes into account several aspects related to heat and mass transfer, crystallization kinetics, and rheological behavior of the considered processing material and allows to evaluate the viscous pull force acting between the internal die walls and the processing material. A finite element scheme has been used to solve the formulated model using suitable boundary conditions.
