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

EPJ 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 ...

Numerical study of the propagation of an adiabatic shear band [PDF]

, 2000
The dynamic propagation of an adiabatic shear band is modellised by numerical simulations. A layer of finite length and finite thickness is submitted to simple shear. After a transient, a steady state is attained in which the shear band propagates with a

Numerical Simulation of Adiabatic Shear-Band Formation in Composites

Automatic Control and Computer Sciences, 2016
The process of plastic flow localization under shear deformations of a composite material consisting from welded steel and copper is studied. A mathematical model describing this physical process is proposed. A new numerical approach based on Courant–Isaacson–Rees scheme is suggested.
