“…Since such factors in the present work. This method was largely described on modify the incompatibility stress, nucleation becomes a consteels, aluminium, and titanium alloys [3][4][5]8,9,20,21] and permits tinuous process and more complicated to predict. To describe correlation between the mechanical parameters and the such a phenomenon, some authors [11,12] have discussed the induced damage.…”

Numerous authors consider that in nodular cast iron, the interface between the graphitic nodule and the ␣-matrix is so weak that nucleation appears suddenly at the beginning of plastic strain. [1,2] Nevertheless, the present experimental study indicates that the nucleation of voids is a continuous process as a function of the imposed mechanical parameters (͚ m , peq ). This result is explained in terms of interaction effects between closely spaced particles. A critical parameter for interaction is determined. Growth kinetics are also investigated and comparison with the Gurson-Tvergaard law allows identification of the q 1 and q 2 parameters of the potential. A critical void volume fraction f c is finally defined and is shown to depend on the stress triaxiality level. At last, the role of the various microstructural heterogeneity levels on the damage kinetics is emphasized. Then, it is clearly demonstrated that all these heterogeneity levels must be considered to estimate a critical interfacial stress.

“…They observed that after onset of damage homogeneous void growth occurred in tension specimens and the average void growth factor was quite similar for all tested specimens. Experiments performed by Brownrigg et al (1983) have shown the dominant effect of hydrostatic tensile stress on growth of voids. Thus, damage criteria which correspond to this kind of evolution of microdefects should take into account a term depending on the first stress invariant which may be seen as the dominating factor regulating the rate of nucleation and isotropic growth of voids.…”

“…The nucleation and coalescence phases are negligible compared to the growth phase, and therefore are not taken into account in this model. Many authors [2][3][4][5][6][7][8][9][10] have shown the important role played by the hydrostatic stress. Therefore, it is expected that this component will appear in the damage function.…”

This paper treats the ductile failure initiation in circumferentially-notched tension specimens and explores the local damage model that is able to represent the continuous degradation of the deforming material. With the aid of finite element calculations, the notched specimens have been simulated numerically and the whole strain-stress history for each geometry derived. This allows determination of the evolution of strain-stress fields until fracture occurs. Two damage models were evaluated: the Rice and Tracey cavity growth model and a model which combines the latter with the plastic strain work, to derive an intrinsic parameter called 'damage work'. These models could predict the location where the crack will initiate as well as the crack initiation step which is reached for a relatively constant value of the critical damage.
