| Abstract: | The fatigue strength of metallic and composite materials under combined static and cyclic loading is analyzed. The analysis
is based on limit-state models, which allow us to describe limiting-stress diagrams of all known shapes, including convex,
rectilinear, S-shaped, and concave. The fatigue strength of the following materials is evaluated: carbon and alloy steels,
aluminum alloys, creep-resistant nickel alloys, unidirectional composites, plastic laminates, glassfiber-reinforced plastics,
and polymers. The calculated results and experimental data are in satisfactory agreement
