摘要
The process of initiation expansion and destruction of damage is discussed by acoustic emission technique. Besides, analysis of damage's evolution process, the type of damage and characteristics of acoustic emission signal are stated in this paper. The result can provide damage forecast for strength test of composite material structure and contribute to development of acoustic emission technique.
