    Abstract

    Shock-loading of a material in contact with a high explosive (HE) experiences a "Taylor wave" (triangular wave) loading profile in contrast to the square-wave loading profile imparted via the impact of a flyer plate. Detailed metallographic and microtextural analysis of the damage evolution in spalled Cu samples as a function of square/triangle and sweeping detonation-wave loading is presented. © 2009 American Institute of Physics.
