The results are presented of examination of the relationships governing low-cycle deformation and failure of the metal of rolled sheets (03Kh16N9M2 steel) with initial anisotropy of the mechanical properties. The results show that the cyclic characteristics of this material depend on the direction in which the specimens are cut out. The given dependence is nonmonotonic. The lowest endurance is recorded for the specimens cut out in the Z-direction normal to the plane of rolled stock. With an increase of the angle ϕ, between the Z axis and the direction in which the specimen is cut out, the endurance increases, and at ϕ⩾ 45° it is almost independent of angle ϕ and corresponds to the values obtained for specimens cut out in the rolling direction. The results of evaluation of the cyclic endurance of specimens obtained on the basis of strain approaches and energy criterion are presented. [ABSTRACT FROM AUTHOR] |
