The present contribution deals with the evaluation of the plastic work induced adiabatic heating during any dynamic loading path considering a wide class of constitutive models including physics based models and phenomenological ones. Various approaches are presented as well as their consequences in terms of adiabatic shear banding onset conditions. Regarding this specific mode of dynamic failure, this work settles on the strong influence of the method retained on estimating the temperature increase. This systematic analysis provides clearly discriminating insight in the field of dynamics of materials.
