The criterion for strength assessment of structures with crack-like defects based on the proposed concept "resistance of material to crack growth" is formulated. This criterion is a characteristic of the stress intensity factor rate changes at the crack tip during its propagation in a considered structural element. The most typical structural elements (sheets, plates, bars, cylindrical shells, etc.) with defects of different shape and location are considered. The examples of residual lifetime and fracture risk assessment of defected structural components with the account of operation factors (loading mode, influence of environments, material state) are presented. This manual is intended for researchers and engineers that work in the field of design, technical diagnostics and exploitation of the critical structures in different branches of industry (mechanical engineering, power generation industry, pipeline transport, etc.) and for the graduate and post-graduate students of corresponding specialties of higher educational schools.
