The paper is devoted to the study of a mathematical model for thethermomechanical evolution of metallic shape memory alloys. The main novelty ofour approach consists in the fact that we include the possibility for thesematerials to exhibit voids during the phase change process. Indeed, in theengineering paper has been recently proved that voids may appear when themixture is produced by the aggregations of powder. Hence, the composition ofthe mixture varies (under either thermal or mechanical actions) in this way:the martensites and the austenite transform into one another whereas the voidsvolume fraction evolves. The first goal of this contribution is hence to statea PDE system capturing all these modelling aspects in order then to establishthe well-posedness of the associated initial-boundary value problem.
