Anisotropic fracture criterion of Ti6Al4V titanium alloy under wide range of strain rates

Wojciech Moćko, Cezary Kostrzewski
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.
