Crack Propagation in Compressor Rotor Blade

Abstract

Turbomachine blading crack propagation and initiations are one of the most important problems. Design, operation and modernization of the contemporary turbomachines are impossible without a detailed numerical and experimental analysis of vibrations on their most important structural elements, i.e. the blades. In addition to determining vibration characteristics, it is often necessary to find the distribution of vibration stresses and their localization. This report is comprised of 4 progress reports for each 6 month period of this effort.
