Inverse analysis for an elastic structure is used to estimate the geometry or the shape for defects and the elastic properties of the structure from additional information such as experimental data of displacements, strain and velocity of the structure subjected to any mechanical loading or constraint. In the present paper, a newly developed inverse technique using genetic algorithm (GA) is presented for identifying several elliptical defects in a square plate subjected to a uni-directional load with various loading directions. The position, the size and the number of internal defects are estimated by using displacement data of the plate and GA. The influence of some parameters in GA upon the final results of inverse analysis is investigated and a new method for estimation of defects is presented.
