The genesis of adiabatic shear bands [PDF]
AbstractAdiabatic shear banding (ASB) is a unique dynamic failure mechanism that results in an unpredicted catastrophic failure due to a concentrated shear deformation mode. It is universally considered as a material or structural instability and as such, ASB is hardly controllable or predictable to some extent.

Adiabatic shearing and performances of milling 304 stainless steel based on cooling strategies of flood, LN2 and LN2+LCO2 [PDF]
During high-speed milling, stainless steel is prone to generating adiabatic shear bands in the cutting zone, which affects the cutting quality. The main factors causing adiabatic shear are high temperature and elastoplastic instability.

On the persistence of adiabatic shear bands [PDF]
It is generally agreed that the initiation and development of adiabatic shear bands (ASBs) are manifestations of damage in metallic materials subjected to high strain rates and large strains as those due to impact in a Hopkinson Bar system.

Adiabatic Shear Localization in Metallic Materials: Review [PDF]
In advanced engineering applications, there has been an increasing demand for the service performance of materials under high-strain-rate conditions where a key phenomenon of adiabatic shear instability is inevitably involved. The presence of adiabatic shear instability is typically associated with large shear strains, high strain rates, and elevated ...

Adiabatic Blanking: Influence of Clearance, Impact Energy, and Velocity on the Blanked Surface
In contrast to other cutting processes, adiabatic blanking typically features high blanking velocities (>3 m/s), which can lead to the formation of adiabatic shear bands in the blanking surface.

Width of adiabatic shear bands [PDF]
AbstractAn 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.
