treatment, involves complex interaction between various aspects: mechanical, thermal and metallurgical
into the material. Therefore, experimental and theoretical studies were conducted to predict these
mechanical impacts in order to optimize the choice of materials to use. In This work we adopt The
Ganghoffer approach usually used in this domain.
This work represents a contribution to the prediction of plasticity of transformation (TRIP) for a
martensitic transformation of the Fe-Ni-C steel. In this regard, a criterion for selecting transformation into
martensite platelets based on the shear mechanical force (SMF). Another originality of this work, is the
development of two numerical models; the first focuses on mono-grain of non regular shape and the
second one concerns the multi-grain scale formed by a set of five grains of different non regular (nonidentical) shapes with a surrounding medium. To validate these models, many numerical simulations were
carried out by imposing more uniaxial and biaxial loads to predict the kinetics and the final value of the
TRIP.
