Dynamic shear band propagation and micro-structure of adiabatic shear band
Computer Methods in Applied Mechanics and Engineering, 2001 A meshfree Galerkin approximation, reproducing kernel particle method, is used in the displacement-based explicit formulation to simulate dynamic shear band propagation as well as microstructures of adiabatic shear bands. The main advantages of using meshfree interpolants are two: (i) it can effectively avoid mesh-alignment sensitivity that finite ...

Microstructure of adiabatic shear bands in Ti6Al4V
Materials Characterization, 2013 Abstract Microstructural deformation mechanisms in adiabatic shear bands in Ti6Al4V are studied using traditional TEM and selected area diffraction, and more advanced microstructural characterisation techniques such as energy dispersive X-ray spectroscopy, high angle annular dark field STEM and conical dark field TEM.

Experiments on formation of the adiabatic shear band in sheet metal
Metals and Materials International, 2005 Formation of the adiabatic shear band in sheet metal is investigated with experiments for high strength steel sheets, 60 C and 60 TRIP. Since the adiabatic shear band is formed as a result of adiabatic shear failure with a narrow band of concentrated ...

Adiabatic shear bands in steel
International Journal of Fracture Mechanics, 1970Abstract : Bands of intense shear have been reported in steels which have been subjected to a high strain rate. It was proposed that these bands were caused by unstable adiabatic shear; that the rate of thermal softening (as heat is generated locally by plastic work) is greater than the rate of work hardening of the metal.

Adiabatic Shear Banding in Plane Strain Problems
Journal of Applied Mechanics, 1989Plane strain thermomechanical deformations of a viscoplastic body are studied with the objective of analyzing the localization of deformation into narrow bands of intense straining. Two different loadings, namely, the top and bottom surfaces subjected to a prescribed tangential velocity, and these two surfaces subjected to a preassigned normal velocity,

Geometrical imperfection and adiabatic shear banding
International Journal of Impact Engineering, 2008Abstract This work addresses the effect of small geometrical imperfections on adiabatic shear band (ASB) formation. The separate effect of the length and radius of short notches is systematically investigated in AM50 and Ti6Al4V alloys, using shear compression specimens.
