Originální abstrakt

The paper presents a new method for a retro-estimation of the stress amplitude, the cyclic ratio and the number of cycles to failure from the fracture morphology of failed structural components. The method is based on a previously proposed procedure using a new relation enabling to describe the whole range of the long crack growth. The method is suitable for quantitative assessment of fatigue loading parameters and the number of cycles spent during the stable propagation. The application possibilities of the method are demonstrated in a case study concerning the fatigue failure of a compressor blade. The method can be also applied in case where a stationary random loading is to be expected. A special software package was also developed for university courses in applied fracture mechanics.
