CHANGE OF MODAL PROPERTIES DUE TO DAMAGE IN BEAM BUCKLING PROBLEM
Lehký D., Frantík P.
pages 359 - 362, full text

The paper is focused on analysis of changes of eigenfrequencies due to local damage in beam buckling problem. The aim is determination of suitable initial parameters for consequent inverse analysis. Relative changes of the first five eigenfrequencies when local damage in individual parts of the beam occurs were studied together with influence of axial force size to those changes. Even with the knowledge of significant simplification, such a task can serves as a prefiguration for damage identification of pre-stressed structures.
