An equation for the half-width of an adiabatic shear band is derived. With reference to the equation, the importance of thermal conductivity, temperature, and viscosity in determining the bandwidth are illustrated. It is shown that calculations of shear band width are fairly close approximations to those obtained experimentally. The apparent insensitivity of shear band width to the loading conditions is in agreement with experimental findings of other researchers.
