摘要
A system for monitoring damage progression in a composite structure includes a load sensor, acoustic emission sensors, a camera, and a monitoring device. The load sensor measures an applied load to the structure. The sensors measure acoustic emission data indicative of possible damage to the structure. The camera captures image data of the structure in a designated portion of the electromagnetic spectrum. The monitoring device executes a method by which the acoustic emission data is synchronously collected with the image data and the applied load. The device automatically maps the acoustic emission data onto the image data to detect an area of damage progression in the composite structure. A failure event in the detected area of damage progression may be predicted using the mapped data, and a control action may be executed in response to the predicted failure event.
