The lecture introduces students to basic methods of evaluation of degradation processes in structural materials. Analyses of microstructural conditions of brittle and ductile fracture initiation, fatigue damage, creep, corrosion damage, corrosion cracking and principle mechanismus of wear of service surfaces are presented. These analyses are followed by comments of effects of temperature, loading mode and environmental parameters on limited state finished by fracture and loss of general function of material consist in bearing stress-strain field. The whole lecture of initiation and propagation mechanisms of degradation processes is aimed on solution of technical problems how to improve reliability and safety of structural parts.
