Dissipation in adiabatic shear bands
Mechanics of Materials, 1994Abstract In the present study of adiabatic shear banding in metals, the region of interest is modelled as a two-material two-temperature body. Specific material laws governing thermoviscous plasticity and heat transfer are ascribed to the shear-band zone.

On stress collapse in adiabatic shear bands
Journal of the Mechanics and Physics of Solids, 1987Abstract T he dynamics of adiabatic shear band formation is considered making use of a simplified thermo/visco/plastic flow law. A new numerical solution is used to follow the growth of a perturbation from initiation, through early growth and severe localization, to a slowly varying terminal configuration.

Modelling of Formation of Adiabatic Shear Bands
Applied Mechanics and Materials, 2014Adiabatic shear bands are microstructural features that appear when metals, and some non-metals are subjected to impact loading at strain rates in excess of 103 s-1 and large strains. The formation of these bands is generally attributed to several competing mechanisms, among them is an initial strain hardening followed by adiabatic thermal softening ...

The Initiation and Growth of Adiabatic Shear Bands
International Journal of Plasticity, 1985Abstract A simple version of thermo/viscoplasticity theory is used to model the formation of adiabatic shear bands in high rate deformation of solids. The one dimensional shearing deformation of a finite slab is considered. For the constitutive assumptions made in this paper, homogeneous shearing produces a stress/strain response curve that always ...

Dynamic recrystallisation in adiabatic shear bands
Le Journal de Physique IV, 2000An XC18 steel material in bcc structure was deformed in double shear with a Hopkinson bar at a projectile speed of 97 m/s With the help of micrographs, the local shear strain distributions have been examined The EBSP technique was used to measure the orientation of the grains from which the orientation distribution function (ODF) was constructed.

Adiabatic shear banding in a bimetallic body
Acta Mechanica, 1989Thermomechanical deformations of a body made of two different materials and under-going simple shearing deformations are studied with the objectives of finding out when and where adiabatic shear bands will initiate and how they will subsequently grow. Each material is modeled as strain and strain-rate hardening but thermally softening.

Numerical modeling of the propagation of an adiabatic shear band
Metallurgical Transactions A, 1986The critical phenomena determining the propagation of an adiabatic shear band occur at its extremity. The stress and strain distributions at the tip of a shear band are calculated as a function of applied shear strain using the finite element method for an elasto-plastic material.
