Method for identifying local damping capacity in composite structures

摘要

The method involves measuring generated oscillations (5, 6) in a lightweight construction component (1), and producing attenuation in the material to be tested with local and directional resolution, where material of the lightweight construction component is made of plastic material such as carbon fiber-strengthened plastic material and glass-fiber reinforced plastic material. A corporate value of a sensor (4) is evaluated by a computational device, and the location, direction and/or the intensity of damage to the material to be tested in or on the lightweight component is calculated.
