Abstract
The objective of this work was to demonstrate the feasibility of nonlinear vibration/acoustic/ultrasonic diagnostic tools to be implemented in a structural health monitoring system for imaging damage. In particular, the sensitivity a second harmonic imaging technique (SHIT) based on material nonlinear elastic effect known as second harmonic generation (SHG) was investigated. Examples of the capability and limitations of the proposed damage detection process to detect and image barely visible impact damage (BVID) due to low velocity impact (
