Claim One:
1. A method of analyzing material properties of a non-rigid body comprising the steps of: (a) establishing a plurality of three-dimensional point correspondences of the non-rigid object in an unstressed and stressed state; (b) from the plurality of point correspondences, generating a finite element model of the non-rigid body having initial material properties and generating a finite element strain distribution; (c) detecting abnormal areas of the non-rigid body by comparing finite element strain levels from the strain distribution; and (d) determining at least one material property of the abnormal areas by: (1) establishing a plurality of boundary point correspondences from the plurality of point correspondences; (2) inputting the boundary point correspondences into the finite element model for generating a predicted set of three-dimensional point correspondences of the non-rigid object in the stressed state; and (3) refining the at least one material property based on a comparison of the predicted set of point correspondences and the set of point correspondences of the non-rigid object in the stressed state until the predicted set of point correspondences and the set of point correspondences of the non-rigid object in the stressed state are within a minimum difference.
