Abstract : The dynamical aspects of solid-solid phase transformations are studied within the framework of the theory of thermoelasticity. A problem of the Riemann type for a one-dimensional bar undergoing an adiabatic process is analyzed. It is shown that by imposing a kinetic relation and a nucleation criterion it is possible to single out a unique solution. This extends to the thermomechanical case results previously found in a purely mechanical context.
