Propagation of Adiabatic Shear Bands [PDF]
Le Journal de Physique IV, 1997 The dynamic propagation of a shear band is assessed in mode II. A layer of finite thickness is subjected to siinple shearing. The band propagates in the shear direction under steady state conditions. A variational approach is developed to calculate the shear band velocity and the length of the process zone.

Size effect during dynamic shear tests with hat-shaped specimens
Journal of Materials Research and Technology, 2023 The failure mechanism and size effect during the quasi-static and dynamic shear tests of hat-shaped specimens were investigated in this study. Three types of specimens with different shear ring thicknesses (800, 400, and 50 μm) were designed.

DYNAMICS OF ADIABATIC SHEAR [PDF]
Le Journal de Physique IV, 1991 The formation of adiabatic shear bands is examined with an approximate analytic model. The shear band is viewed as a propagating feature with a well-defined front. The shear band is further partition into a shear-band process zone within which most of the adiabatic heating and shear stress relaxation occurs, followed by a quasi-steady zone within which
