In this work, we model the basic mechanisms of the interaction between phase-transformations and plasticity within a one-dimensional constitutive framework. Efficient algorithms are presented, facilitating to solve the underlying evolution equations with high numerical stability at low numerical costs. Furthermore, a family of functions covering physically reasonable classes for the inheritance of plasticity in the context of evolving phases is proposed and discussed by means of several representative numerical examples.
