In the several engineering fields, biological, sports, aeronautical and aerospace engineering for example, identification of pressure distribution applied on the structure in a very important issue, therefore some expirimental techniques have been suggested to measure the distributed load by piezo-electric sensors or films. However, such a direct measurement often meet with difficulty, because the geometry or rigidity of the contact surface may be altered by attaching the sensors on the surface. In order to overcome the difficulty, this paper deals with estimation of pressure distribution applied on the structure employing the technique of inverse analysis. In the present study, the transmission matrix is introduced which gives linear relation between distributed load and internal strain. Tikhonov's method and truncation of singular value decomposition (TSVD) are used to stabilize the solutions of the inverse analysis. A numerical demonstration for the estimation of foot pressure applied on a rectangular plate is conducted to illustrate the effectiveness of the present numerical formulation to identify the pressure distribution.
