The approach takes into account the effect of stress state on damage and failure criteria. Different branches of these conditions are considered corresponding to various microscopic mechanisms depending on stress states. To validate the proposed framework experiments with biaxially loaded specimens and corresponding numerical simulations have been performed. Geometries of different specimens are discussed to analyze a wide range of stress triaxialities and Lode parameters. Digital image correlation technique has been used to analyze current strain states in critical regions of the specimens. Combination of experiments and numerical simulations greatly enriches understanding of damage and fracture processes of ductile metals.
