The paper describes the way how to find the material parameters of the homogenous isotropic or orthotropic 2D continuum from measurements of deformation of selected nodes. The FE method is used for reconstruction of the stiffness matrix. The developed method enables to determine the angle between the material axes of the continuum and the local coordinate system of the used elements.
