The effects of edge cracks on the natural frequencies of cracked cantilever beams have been extensively studied by Wendtland (1972). These results are referred to by quite a number of related journal papers; the refernce is:
Wendtland D. A¨ nderung der biegeegenfrequenzen einer idealisierten Schaufel durch Risse. Ph.D. Dissertation, University of Karlsruhe; 1972.
Does anyone know how this can be accessed online, or atleast the complete set of results for eigenfrequency (first three modes of vibration) changes due to edge cracks at different positions and depths?
