A Gurson-type layer model for ductile porous solids with isotropic and kinematic hardening

“…Benzerga and Leblond (2010); Pineau et al (2016) ;Benzerga et al (2016) for recent reviews of the topic): (i) the nucleation of voids, (ii) their growth, change of shape and rotation, and finally (iii) their coalescence leading to final failure.…”

Effect of void cluster on ductile failure evolution

“…Early models for void growth in such situations were developed by McClintock (1968) and Rice and Tracey (1969), and subsequently a large amount of research has focussed on this area (see reviews by Garrison and Moody, 1987;Tvergaard, 1990;Benzerga and Leblond, 2010;Benzerga et al, 2016). The most widely known porous ductile material model is that developed by Gurson (1977) and subsequently extended (Tvergaard, 1981;Tvergaard and Needleman, 1984).…”

A porous crystal plasticity constitutive model for ductile deformation and failure in porous single crystals

“…The above works suggests it is necessary to develop a crystal plasticity based constitutive model that accounts for the effect of mechanics based quantities, such as stress triaxiality, initial porosity, and crystal orientation inside individual grains, on the overall deformation and failure. There has been significant research performed in this area in the recent past, these works have been thoroughly reviewed and discussed in the literature, for example by incorporating crystallographic aspect for anisotropic behaviour ( [14], [22]- [26] and references there in) or anisotropy through phenomenological plasticity models (for details see [26]- [28]). These works are based on Gurson type approach (for details see [25]- [28] and references therein), and homogenisation approaches ( [14], [22]- [24]).…”

In the proposed work, an approach similar to [1] has been used to incorporate the void growth and coalescence effect in a crystal plasticity based constitutive model in a phenomenological context.…”
