Abstract Experimental diagrams of limiting states of active systems under conditions of mechano-sliding fatigue are presented, as well as their analytical description. A graphical representation of the proposed equations for limit stresses (limits of mechano-sliding fatigue) is given based on the energy criterion of limiting states in the form of multicriteria diagrams of limiting states of various active systems (the ordinate axis on them serves as a strength scale, and the abscissa axis – as a tribological scale). Analysis of the proposed equations for limiting stresses, experimental diagrams of limiting states of different active systems showed that: 1) processes of friction and wear, depending on the conditions of their implementation, can significantly reduce, as well as significantly increase, the fatigue resistance of the active system; 2) cyclic stresses, depending on the test conditions, can both significantly reduce and increase the wear resistance of the active system.
Keywords mechano-sliding fatigue, active system, limiting state diagram, fatigue limit, energy criterion, direct effect, reverse effect
