On what controls the spacing of spontaneous adiabatic shear bands in collapsing thick-walled cylinders [PDF]

open access: yesEPJ Web of Conferences, 2015
Shear bands formation in collapsing thick walled cylinders occurs in a spontaneous manner. The advantage of examining spontaneous, as opposed to forced shear localization, is that it highlights the inherent susceptibility of the material to adiabatic ...

ADIABATIC SHEAR BAND VELOCITIES [PDF]

open access: yesLe Journal de Physique Colloques, 1985
A new method of investigating adiabatic shear band velocities under hydrodynamic pressure is described. Interpretation of propagation rates depends on an appreciation of the stress and strain fields into which propagation occurs. The C-HEMP computer code has been used to characterize load histories, and results are described for comparison with the ...

Mechanistic Prediction of Adiabatic Shear Bands in 2024-T351 Aluminium [PDF]

open access: yes, 2021
In some materials such as grade 2024-T351 aluminium, high speed deformation can result in a phenomenon known as adiabatic shear bands. In events such as ballistic impact, adiabatic shear bands can be a very low energy precursor to catastrophic material ...

Multiple Deformation Mechanisms in Adiabatic Shear Bands of a Titanium Alloy during High Strain Rate Deformation. [PDF]

open access: yesMaterials (Basel)
The occurrence of adiabatic shear bands, as an instability phenomenon, is viewed as a precursor to failure caused by instability at high strain rates. Metastable β titanium alloys are extensively utilized due to their excellent mechanical properties,

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.

Calorimetric consequences of thermal softening in Johnson–Cook’s model [PDF]

open access: yes, 2013
At high loading rates, the development of adiabatic shear bands in metals is conventionally attributed to the strong interactions induced by viscoplastic dissipation within the bands and thermal softening effects.

Thermomechanical Variational Principles for Dissipative Materials with Application to Strain Localization in Bulk Metallic Glasses [PDF]

open access: yes, 2004
This thesis is concerned with variational principles for general coupled thermomechanical problems in dissipative materials including finite elastic and plastic deformation, non-Newtonian viscosity, rate sensitivity, arbitrary flow and hardening rule, as
