【 摘 要 】

We consider a viscoplastic problem with contact condition modelling the thermomechanical deformations during casting of aluminium alloy slabs. We introduce a fictitious domain method to impose the metallostatic pressure on the thermal free boundary. Finally, we present some numerical results for a particular casting process during both the start and stationary stages. (C) 2000 Elsevier Science B.V. All rights reserved.
