heal.abstract	Previously introduced yield criteria, taking into consideration the influence of internal dilation of the materials during yielding, were based on a conventional assumption of the influence of the hydrostatic component of stresses on the yielding process. They were fitted to the actual macroscopic behaviour of the materials and they were proved experimentally to predict the overall plastic behaviour of a great number of substances. In this paper a yield criterion was tested, which was based on the theory of void growth and coalescence in the vicinity of internal discontinuities of the material during yielding and fracture. The inverse dependence of yielding on the hydrostatic tension was incorporated, in the criterion and it was shown that an increase of the hydrostatic component creates a rapid decrease of fracture ductility. © 1986 Pitagora Editrice Bologna.	en
