Abstract

An expression of the macroscopic criteria of perfectly plastic rigid matrix containing penny shaped crack is presented. The proposed approach, derived in the framework of the limit analysis, consists in the consideration of Eshelby-like trial velocity fields for the determination of the macroscopic dissipation. The obtained criterion significantly improves existing ones for ductile cracked media (see for instance Gologanu et al. [2] and Ponte Castañeda and Suquet [8]).
