They were a temperature-displacement coupled analysis, which was a geometrically and physically non-linear issue. The obtained results of calculations confirmed the sufficient strength of the structure of this extruder zone. The professional ABAQUS® software was used for the computations. Keyphrases: active grooved feed zone of the extruder, finite element method, polymeric materials
