Tymoshenka Institute of Mechanics of the National Academy of Sciences of Ukraine popup.description2 The models of long-term failure due to multicycle fatigue under uniaxial asymmetric and biaxial combined static and cyclic loading conditions have been developed. The problems of the computation of the number of cycles before failure due to classical (multicycle) fatigue in cases of: prismatic rods under uniaxial asymmetric tension-compression; thin-walled cylindrical shells under combined loading of uniaxial tension-compression and torsion; thin-walled walled cylindrical shells under combined loading of bending and torsion have been solved. The solutions are based on the concepts of equivalent stresses for which structure follows the hypothesis of: the existence of unique isochronous diagrams of limiting stresses using the power transcendental functions the classical failure criteria. The criterion of maximum normal stresses, the criterion of maximum tangential stresses, and the criterion of the specific strain energy due to distortion were used as classical failure criteria. The calculation results have been confirmed experimentally. Product Description popup.authors Hlemeida Serhii K. Golub Vladislav Petrovich Danylchenko Svitlana Borysivna Kaminska Olena A.
