A viable model for the phenomenon of transformation induced plasticity must be able to predict the strain response to arbitrary, also non-proportional loading paths. The constitutive model presented in this paper is interfacing between the macro- and the mesoscale by stress partitioning in the parent and product phase, using a nonlinear scale transition rule. As one of the key features a mean field tensor representing the orientation strain contribution is introduced taking into account backstress effects. A good agreement of the model results with experiments on a maraging steel is achieved. (C) 2012 Elsevier Ltd. All rights reserved.
