ADIABATIC SHEAR BAND VELOCITIES [PDF]
Le 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 ...

Effect of high strain rate on adiabatic shear susceptibility and microstructures in Al0.4CoCrFeNi high-entropy alloy [PDF]
Journal of Materials Research and TechnologyThe effect of high strain rate on adiabatic shear susceptibility and microstructures in Al0.4CoCrFeNi high-entropy alloy (HEA) was examined using a split Hopkinson pressure bar (SHPB) and hat-shaped specimens. The results exhibit a clear strain-hardening

Evolution of Adiabatic Shear Band in Ultra-Fine-Grained Iron under Dynamic Shear Loading [PDF]
, 2011 Ultra-fine-grained (UFG)/Nanocrystalline (NC) materials usually show reduced strain hardening and limited ductility due to formation of adiabatic shear band (ASB) under dynamic loading. In the present study, evolution of ASB in UFG Fe under dynamic shear

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

Adiabatic Shear Banding in Nickel and Nickel-Based Superalloys: A Review
Metals, 2022 This review paper discusses the formation and propagation of adiabatic shear bands in nickel-based superalloys. The formation of adiabatic shear bands (ASBs) is a unique dynamic phenomenon that typically precedes catastrophic, unpredicted failure in many

The genesis of adiabatic shear bands
Scientific 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.
