Abstract: Load reconstruction is an important part of perceptionalsmart structure researches. The paper presents the result of loadreconstruction on a perceptional laminated plate. Based on the elastic waveand lamination theory, a forward wave model of orthotropic laminated platesis built with state-space equations. By defining an error index J, the timehistory and position of the applied load are determined by an optimalarithmetic and linear searches. Finally, the methods in the paper are allverified by examples.
