The new fracture criterion taking into account stress triaxiality, strain rate and anisotropy is introduced in this paper. The model is capable to predict the influence of the loading direction on the fracture strain. The equation is applied to estimate the fracture locus of Ti6Al4V titanium alloy under quasi-static and dynamic loading regimes.
