| Research Abstract |
In the present research, a real-time identification method on impact location and force is established for foreign object impact of CFRP laminated plates, stiffened panels and FW tanks with piezoelectric sensors, based on the experimental impact force identification method. Further, a damage monitoring technique to monitor impact damages in real-time is developed by using the identified maximum impact force.
