DAMAGE POSITION AND GRADE SELF-DIAGNOSTIC SMART COMPOSITE MATERIAL

Smart material and structure are the research focus of many researchers recently. This article introduces a kind of self-diagnostic smart structure which can self-diagnose the damage in real time and in a large area. The damage position and its grade can both be decided. Introduced in detail in this article are the manufacture of the smart composite test-specimen,the research of the four element arrangements and the signal processing using pattern recognition algorithm. This system can work well.
