    Kinetics of accumulation of deformations and damages in the event of a cyclic rolling contact

    The poorly known mechanism of failure, namely, a shear in a surface layer in the event of a cyclic rolling contact is considered. The means of analysis of a mechanism have been developed that allow the estimat...

    Conditions for existence of alternating inelastic deformations at low-cycle loading

    The criterion of the existence of an alternating flow and low-cycle fatigue used at present can give substantial (up to two times) errors in the strength margin. A more accurate universal criterion and the sof...
