dc.description.abstract | The contact fatigue is a localized phenomenon that occurs in highly
stressed local zone of the material under the loaded contact region and as such is
highly nonlinear problem. This phenomenon exists in almost all real mechanical
systems with contact strains coupled with other sources of nonlinear behaviour.
The improvements of existing procedures and methods for standard calculation
of contact fatigue have a potential to give significant contribution to increase
accuracy of calculation of life assessment, reliability and efficiency of complex
mechanical systems. This paper gives the basic explanation of the Theory of
critical distances and its application on direct estimation of fatigue crack
initiation in contact zones. Analysis of contact fatigue when the contact zones
are subjected to additional nonlinearities such as geometry manufacturing
deviations, geometry microscale-damages or nonlinear material characteristics
are presented in detail. Few different real multi-nonlinear problems are used for
analysis performing. The benefits of presented approach are discussed by detail
analysis of the obtained results, and could be based on the increasing accuracy
of contact fatigue prediction considering all existing nonlinearities in loaded
contact zones of complex mechanical systems. | sr |
