A simple approach for the modeling of an ODS steel mechanical behavior in pilgering conditions

► The mechanical behavior of an ODS steel is investigated under pilgering conditions. ► Two mechanical tests show different trends, and are described with a simple model. ► Model parameters are identified using one sample, and considering strain range changes. ► The constitutive model involves few parameters but their values are strain path dependent. ► One identified set of parameters would be appropriate for FEM modeling of pilgering.
