An experimental identification method of impact force location and history acting on CFRP stiffened panels is presented. The relation between force histories and strain responses under single loading is first determined experimentally by using measured force histories with impulse hammer and the corresponding strain responses at the discrete points. By employing this relation, the locations and histories of multiple impact forces is identified using measured strain responses based on the mathematical programming method. The validity of the present identification method has been verified through the impact test of CFRP stiffened panels using biaxial strain gauges attached on the surface of the panel. The accurate force location and force history can be identified for both single and multiple loading.
