Dependence of dangerous volumes on the ratio between contact and non-contact forces in roller/shaft tribo-fatigue system
The paper discusses mechanical and mathematical models of stress-strain state and state of volumetric of damage of roller/shaft model operating under the complex loading by contact and bending forces. Application of non-contact loads to this tribo-fatigue system crucially changes the picture of distribution of stresses and strains in the contact interaction. Significant changes of qualitative and quantitative characteristics of stress state and dangerous volumes in three-dimensionalneighborhood of the contact area are shown.
