초음파 현미경 및 AE에 의한 결함 측정
- Published : 1991.12.01
Abstract
Acoustic microscopy has attracted much interest recently as potential nondestructive evaluation technique for detecting and sizing defects of surface and sub-surface. Also acoustic emission testing method has been developed for detecting microcracks which is more than 30
