Detection and Location of Flaw Growth in Metallic and Composite Structures

Source

The application of a multichannel real-time acoustic emission location system to the detection and location of structural defects in three different materials and geometries is presented. Test results from welded steel pressure vessels demonstrate that incremental crack growth during pressurization can be accurately located and assessed. Additional results from graphite-epoxy honeycomb structures indicate that acoustic emission is also a viable tool in detecting and locating impending failure in composite materials.
