X-Ray tomography of incipient spall in laser shocked aluminum (original) (raw)

2001

Abstract

Incipient spallation damage was studied in Aluminum non-destructively using 3D X-ray tomography. Two samples were laser shocked and recovered using a weaker and stronger laser pulses. The X-ray tomography was performed at SSRL with a resolution of five microns. The 3D distribution of damage in both samples was clearly evident about a well defined spall plane. The results were analyzed
