Abstract: In this paper the boundary element method and Kalman filter are used to solve the inverse problem for material parameters of orthotropic plane elastic problem. The constants ν12 and G12 of a material may be found with only several known displacements at some observation points. The numerical examples show that this method is valid.

Key words: orthotropic, inverse problem of material parameters,
