The present paper deals with identification of location and history of impact forces which act on aluminum alloy plates. A transfer matrix to relate an impact force to sensor responses is determined based on high-velocity impact tests. The location and history of applied force are evaluated as solution of error minimization problem by using the transfer matrix and measured strain responses. The identification of applied force history can be achieved by solving an inverse problem where a penalty on the force history is imposed in this paper. The validity of the present identification method is examined through the numerical examples.
