摘要：

Some results of experimental and theoretic low-cycle fatigue investigation of notched specimens produced from anisotropic steels are presented. For evaluating the magnitude of local stress and strain in notched specimens, cut out under different angles to the axes anisotropy, interpolation equation was used. It is based on energy relations and equations of Hill's theory of plasticity for anisotropic materials. The number of cycles before fracture was evaluated by using modificed low-cycle fatigue equation of Coffin-Manson, taking into account orientation and values of normal strains and stress to the axes of anisotropy. Satisfactory coincidence of theoretic and experimental durability of notched specimens under low-cycle tension-compression loading was obtained.
