The collective behavior and spacing of adiabatic shear bands in the explosive cladding plate interface

Large assemblages (∼150) of adiabatic shear bands (ASBs) on the titanium side in the titanium/mild steel explosive cladding plate interface were investigated. The change of spacing and length of ASBs initiating at the wavy interface was characterized as periodic and the behavior of ASBs was organized. The observed shear band spacing was compared with existing theories based on a perturbation analysis and on momentum diffusion. A model calculated the ASBs spacing was proposed. The effect of applied loads and the pre-deformation on the shear band spacing was delineated.
