This paper presents a thermo-mechanical approach of solidification in casting processes. A three-dimensional finite element analysis is presented. After a brief recall of the heat transfer computation, the mechanical model is detailed. The casting alloy behavior is modeled by a thermo-elastic-viscoplastic model, while the mould is assumed rigid. A mixed velocity-pressure formulation has been developed, using tetrahedral P1{sup +}-P1 elements. The complete thermo-mechanical coupling--not detailed here--has been implemented in Thercast3 software for 3D casting simulation. The validation is established on a cylindrical solidification test, and an example of application to an industrial casting is given.
