    Abstract
  • A series of plate impact experiments were conducted to probe into the free-surface velocity profiles characteristics of ultra-pure aluminum (Purity:99.999%) by a velocity interferometer system for any reflector (VISAR). Based on the observed differences of pullback signals in amplitude, pulse width, and two sudden changes, the wave profile evolution during fracture process of ultra-pure aluminum from incipient spall to complete rupture is discussed in detail. The reasons for these change behaviors are analyzed with the mesoscopic analysis of soft-recovery sample. This paper points out that these characteristics are possibly related to the release rate of stress wave energy and the fracture behavior of material grain. These analysis results are helpful to understand the evolution process of ductile metal dynamic damage.
