We constructed an isotropic interaction potential for a set of classical identical particles that displays a discontinuous change of its crystalline ground state when a parameter is varied. We used this model to study some properties associated to martensitic transformations. We concentrate here on the triangular-rombohedral transformation in two dimensions, focusing on the hysteresis of the transition, and present also results for the superelasticity effect.
