Ab initio calculations of structural phase transition and mechanical stability of zinc-blende InN compound have been conducted in this work using the pseudopotential plane-wave method within the generalized gradient approximation. The first transition pressure of the material in question has been determined and compared to the data available in the literature. In addition, the mechanical stability criteria have been checked which indicate that zinc-blende InN is mechanically stable for all pressures of interest up to the transition pressure.
