Presents a general approach to the problem of reconstruction of the inhomogeneous pre-stressed state in an elastic body on its amplitude-frequency response, measured in part of its border. Based on the previously defined generalized reciprocity is the ratio of the sequence of linear ill-posed problems, allowing for refinement of the procedure for pre-stress tensor component. As an example, presented a series of computational experiments on the restoration of monotone functions of the distribution of pre-stressed state the problem of bending vibrations of a rod.
