IN-SITU SCANNING ACOUSTIC MICROSCOPY OF CRACK BRIDGING IN ALUMINA
High-resolution scanning acoustic microscopy has been used to observe crack bridging in a fine-grained polycrystalline alumina. The microscope is sensitive to the increased acoustic transmission across the crack from the interlocking and sliding asperities that cause crack shielding and -curve behav...
