Résumé : |
A hybrid non-destructive testing [NU) approach has heen develaped to characterize composites damage using simultaneously bulk and guided ultrasonic waves, acoustic emission, and passive and active infrared thermography. Combining multiple NDT techniques makes it possible to
optimize the diagnosis of a material's structural health. |
