Development of methods of structural materials service life-time prediction through creep and high-cyclic fatigue processes under the uniaxial and complex stress state

popup.description2

The relevance of the research problem is justified and the statement of the research problem is formulated. Recommendations have been developed for determining the long-term strength characteristics of structural materials and for predicting the durability of structural elements due to creep and high-cycle fatigue. The recommendations are based on long-term failure criteria and models that take into account the influence of the type of stress state. The long-term strength and multi-cycle fatigue characteristics of some metallic and polymeric materials have been predicted. The problems of computing the durability of prismatic rods and thin-walled cylindrical shells due to creep and classical fatigue processes under uniaxial and biaxial loading conditions have been solved.
