DAMAGE PARAMETERS IDENTIFICATION IN ELASTIC ROD USING BOTH FINITE ELEMENT AND EXPERIMENTAL ANALYSIS OF FLEXURAL VIBRATION MODES
Abstract
The results of finite-element analysis and experimental investigations of the cantilever elastic notched bar flexural modes are presented. The application of the kinking coordinate and tangent angle on the eigenform graphs under the transition through the damage point as a complex diagnostic property of the location and bar damage degree is offered.
