In the paper the results of the benchmark between experimental trials and FEM outputs of the two previous editions (2007 held in Bologna and 2009 held in Dortmund) are presented and discussed. The dies design is initially introduced and explained in detail in order to clarify which phenomena would be analyzed with the selected design. Experimental trials are then presented with a particular focus on the monitored data; information on trial repetition are also provided. Then a summary of the different FEM codes approaches, of the computational times, of the main outputs and their comparison with experimental results are presented for both conference editions. Profile lengths, die and profile temperatures, process load and die deflections were used as benchmarking parameters for FEM comparison. A detailed discussion for all output parameters is realized in order to understand the potentials and limits of each code. Finally a discussion on future perspective for FE code application and on the next benchmark edition is reported.

Abstract
In the paper the results of the benchmark between experimental trials and FEM outputs of the two previous editions (2007 held in Bologna and 2009 held in Dortmund) are presented and discussed. The dies design is initially introduced and explained in detail in order to clarify which phenomena would be analyzed with the selected design. Experimental trials are then presented with a particular focus on the monitored data; information on trial repetition are also provided. Then a summary of the different FEM codes approaches, of the computational times, of the main outputs and their comparison with experimental results are presented for both conference editions. Profile lengths, die and profile temperatures, process load and die deflections were used as benchmarking parameters for FEM comparison. A detailed discussion for all output parameters is realized in order to understand the potentials and limits of each code. Finally a discussion on future perspective for FE code application and on the next benchmark edition is reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
