Iso‐Work‐Rate Weighted‐Taylor Homogenization Scheme for Multiphase Steels Assisted by Transformation‐induced Plasticity Effect
A simple homogenization scheme for multiphase microstructure (composite) is developed. This scheme is based on the classical Taylor (iso‐strain‐rate) averaging scheme. Scalar multipliers are introduced as weighting parameters in order to relax the condition of uniform strain distribution used in the...

| description | A simple homogenization scheme for multiphase microstructure (composite) is developed. This scheme is based on the classical Taylor (iso‐strain‐rate) averaging scheme. Scalar multipliers are introduced as weighting parameters in order to relax the condition of uniform strain distribution used in the classical Taylor scheme. In the present work, the scalar weighting parameters are determined by satisfying the iso‐work‐rate condition, i.e., work is equally distributed in all constituent phases. In combination with micromechanical models developed for transformation‐induced plasticity (TRIP) effect, the iso‐work‐rate weighted‐Taylor scheme is applied for simulating the effective mechanical behaviour of multiphase TRIP‐assisted steel. The predictions of the iso‐work‐rate weighted‐Taylor scheme are compared with the result of the corresponding simulation with the direct finite‐element method (FEM). |
