A phenomenological two-phase constitutive model for porous shape memory alloys

► A two-phase constitutive model for porous shape memory alloys (SMAs) has been proposed. ► The porosity dependent elastic and plastic material parameters were calibrated using the void cell calculations. ► The proposed model captures the deformation behavior of the void cell calculation after calibrations. ► It is found that the proposed model is capable of predicting the deformation behavior of porous shape memory alloys. ► A couple of finite element based applications are presented showing a good agreement with the experimental results.
