Abstract
Variety of practically important systems (active systems) such as toothings, wheel/rail etc. work in conditions of complex stress–strain state caused by both spatial contact interaction and general non-contact volume deformation (for example bending). Analysis of interaction and damageability of elements of such tribo-fatigue systems is based on statistical model of deformable rigid body with dangerous volume that contains the criteria for limitation of dangerous volumes and the general procedure of their calculation. Dangerous volumes are finite three-dimensional regions where the stress tensor components or equivalent stress exceed the minimum values of fatigue limit distribution. irreversible damages (primary cracks) have higher probability where corresponding dangerous volumes intersect. Results of numerical calculation of various dangerous volumes and their visualization are presented.
