Evolution of spall-damage in iron caused by repeated plate impacts: Ultrasonic evaluation Reviewed International journal
N. Nishimura , K. Fujimoto , Y. Ogi , T. Ito
Ultrasonics 83 88 - 93 2018.01
Language：English Publishing type：Research paper (scientific journal) Publisher：Elsevier
This paper focuses on the developed of spall-damage that occurs in pure iron as a result of repeated
impact. The employed low-frequency scanning acoustic microscopy (LF-SAM) observations combined
with the measurements of ultrasonic wave velocity, attenuation, backscattering intensity and amplitude
spectrum of the reflected wave, enabled us to provide a nondestructive evaluation. The spall-damage distribution
was analyzed in the C-scan images, and we found the spall-damage increase with impact stress
when the latter exceeds the characteristic spall-threshold stress. Moreover, we recorded the decreased
sound velocity, amplitude ratio, and the increase of backscattering intensity, significant attenuation
(the high frequency component of the reflected wave) for enhanced impact stress. It was also demonstrated
that the tiny cracks generated in iron develop significantly during subsequent impacts either with
lower or higher impact stress. Since the presented results concern for the first time the multiple-impact
experiments, we contend that the applied ultrasonic investigations constitute the effective method of
nondestructive spall-damage evaluation. -
