Abstract
We investigate interfacial motions between martensitic variants. Analytically, we describe simply the topology and kinematics of a representative volume constituted of several compatible variants whose interfaces have a velocity differing from those of the material particles. The corresponding driving force is deduced using Eshelby's energy momentum formalism and compared with a critical threshold from which we define a reorientation criterion. The interface movement is taken into account via the concept of an inclusion with moving boundary and we propose a formulation of the global behaviour.
