MODAL VIBRODIAGNOSTICS OF LINEAR DISTRIBUTED SYSTEMS BY THE PRONY METHOD

The modal vibrodiagnostics method, proposed by Prony for the concentrated [lamped] systems, has been adapted for the linear distributed systems. The modal vibrodiagnostics of thin plates and shells is realized by exciting low-frequency bending vibrations. Results of the modal vibrodiagnostics of a cracked thin disc are presented,
