Abstract

An experimental identification method of impact force location and history acting on CFRP laminated plates is presented. The relation between force histories and strain responses is first determined experimentally by using measured force histories and the corresponding strain responses at the discrete points. By employing this relation, the location and history of impact force 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 laminated plate with embedded PZT piezoelectric sensors and CFRP stiffened panel using biaxial strain gauges attached on the surface of the panel. The method is also applied to the impact force identification of CFRP plate involving impact damages such as delamination.
