The α radioactive decay of Pu by self-irradiation in the δ-Pu alloy markedly changes its microstructure and macro mechanical properties. Helium bubbles, the main product of self-irradiation, can affect the plastic behavior of δ-Pu by impeding the movement of dislocations. In this paper, we first derive a relationship between the volume ratio of helium bubbles and aged time. We then introduce the effect of helium bubbles on the critical resolved shear stress for dislocation motion and the growth law for helium bubbles into a constitutive model to obtain the dislocation-based static constitutive functions of δ-Pu. Model parameters are then fitted using experiment data. Finally, the stress-strain curves of δ-Pu for different aged times are presented.
