Aluminium Profiles Extrusion Process Analysis: Mechanical aspects

The presented paper subject is the engineering analysis of the aluminum profiles hot extrusion. Some principal solutions to the process were developed in the paper: billet friction by liner; the plastic flow model in dummy block region; the stress state and flow beginning relations in the die opening zone. General model of stable metal flow relations in the billet volume was formulated. The analysis of all mentioned above problems fulfilled by the uniform methodology with the necessary simplifications.
