Abstract
In the structural health monitoring of aircraft structures, it is important to establish a real-time identification method of an impact location and a force history acting on aircraft wings and fuselages. This paper presents an experimental identification method of the impact force using sensor response. Through the impact test of CFRP laminated plates and stiffened panels, it is shown that the force history and the force location can be identified within several seconds, and they agree well with the experimental ones. A simple damage monitoring method is also presented using the identified impact force, and the validity of the method is verified through the laminated plates under a drop-weight impact test.
