The genesis of adiabatic shear bands [PDF]

open access: yesScientific Reports, 2016
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]

open access: yesScientific Reports
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]

open access: yesEPJ Web of Conferences, 2012
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]

open access: yesMaterials
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 ...

Numerical Simulation of Adiabatic Shear Bands Formation in Composites

open access: yesМоделирование и анализ информационных систем, 2016
The process of plastic flow localization under shear deformations of a composite material consisting from welded steel and copper is studied. A mathematical model describing this physical process is proposed.

Adiabatic Blanking: Influence of Clearance, Impact Energy, and Velocity on the Blanked Surface

open access: yesJournal of Manufacturing and Materials Processing, 2021
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]

open access: yesMaterials Science and Technology, 1985
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.
