Abstract:
This paper considers the inverse problem of reconstructing three inhomogeneous characteristics of a rod (Young’s modulus, shear modulus, and density) from amplitude-frequency characteristics for the regime of steady-state longitudinal, flexural, and torsional vibrations. The unknown characteristics are identified by constructing iterative processes based on the apparatus of the Fredholm integral equations of the first and the second kind. Results of numerical experiments are presented.
