This paper presents the identification of impact forces acting on sandwich panels, and also the detection oftheimpact-induced damagebased on theidentified impact force.In thepresent study, the impact location and the force history are identified using the radiated sound at impact which is measured with microphones. The impact location is identified using the differences in the arrival times of the sound wave at the microphones. The force history is determined from the measured sound pressuredoi:10.6089/jscm.41.85 fatcat:vphlyfsxezdfjc4kza72hlj7gm
