Popis:	Two finite element plane strain models of the same closed die forming process are compared with ABAQUS software. This work is prepared in the frame work of Work Package n°3 of the Virtual Intelligent Forging Coordination Action. The subject of this benchmark is a thermo mechanical upsetting with a screw press of an Inconel workpiece with an initial temperature equal to 1230°C between two warm shaped dies. The first simulation uses the classical implicit quasi static algorithm, the second one uses an explicit scheme without mass scaling with the actual kinematic conditions of the process. Significant discrepancies in the final shape of the workpiece are found.
