Popis:	Field-assisted sintering technology (FAST) implies a multifield problem between electrical, thermal and mechanical fields. Based on a constitutive model proposed in [1], the numerical treatment of the three-field problem in a monolithic finite element framework is discussed. Apart from algorithmic considerations, numerical simulations are performed treating the complex contact problem, large deformations and the multifield issues themselves. This is combined with a PID-controller, which is required when the temperature process is given at specific positions in the graphite tool system and the electrical current is uncertain. The numerical simulations are validated by real experiments.
