Adiabatic shear banding (ASB) is a precursor of failure of high strength metals and alloys when submitted to impact and other high strain rate loading. As a mechanism of plastic flow localization triggered by a thermo-mechanical instability in the context of dynamic plasticity, ASB causes a discontinuity of the strain/strain rate field. In the present paper, some models available in literature are assessed regarding their ability to reproduce ASB features and further consequences. Some tracks for further developments in the field are also given.
