Experiment of the Formation of Adiabatic Shear band in Sheet Metal [PDF]

open access: yes, 2000
The adiabatic shear band formation is one of the high speed deformation phenomena, in which adiabatic shear failure is physically observed as a narrow band of the continuous shear strain.

Adiabatic shear band formation as a result of cryogenic CNC machining of elastomers [PDF]

open access: yes, 2011
The traditional method for producing polymer-based products is the use of moulding technologies such as injection moulding. CNC machining methods are predominantly used for metal part manufacture. The use of CNC machining methods for direct machining of

Research on adiabatic shear failure character of pure copper and aluminum bronze based on empirical electron theory

open access: yesAIP Advances, 2017
The valence electron structure (VES) parameters affecting adiabatic shearing failure under high speed impact load using split Hopkinson pressure bar (SHPB) were studied by empirical electron theory (EET) of solids and molecules.

Meteorite impact shatter cones – adiabatic shear bands? [PDF]

open access: yes, 2009
Shatter cones are distinctive, striated, conical fractures found in shocked rocks at meteorite impact structures. They are estimated to form at shock pressures from 2 to 25 GPa and range in size from a few millimeters up to more than 10 meters in length.

Analytical solution for shear bands in cold-rolled 1018 steel

open access: yesJournal of the Mechanical Behavior of Materials, 2012
Cold-rolled 1018 (CR-1018) carbon steel has been well known for its susceptibility to adiabatic shear banding under dynamic loadings. Analysis of these localizations highly depends on the selection of the constitutive model.

Critical adiabatic shear strength of low alloy steel under compressive loading [PDF]

open access: yes, 2022
S.657-674The adiabatic shear band phenomenon is investigated by means of a Split-Hopkinson-Pressure bar with dies, which produce a shear loading in the specimen.

Adiabatic shear localization: occurrence, theories, and applications [PDF]

open access: yes, 1992
Adiabatic shear localization is a mode of failure that occurs in dynamic loading. It is characterized by thermal softening occurring over a very narrow region of a material and is usually a precursor to ductile fracture and catastrophic failure.

Mechanical behavior of ultrafine-grained materials under combined static and dynamic loadings

open access: yesEPJ Web of Conferences, 2015
Ultrafine-grained (UFG) materials have extensive prospects for engineering application due to their excellent mechanical properties. However, the grain size decrease reduces their strain hardening ability and makes UFG materials more susceptible to ...

Microstructural model for shear strain localization and occurrence of adiabatic shear band at high strain rates [PDF]

open access: yes, 2009
The occurrence of adiabatic shear bands during high strain rate deformation of metals has been analyzed using a finite element approach. It was found that these bands occur at inhomogeneities in the microstructure and result from the competing processes ...
