Approaches to model structural and contact fatigue
Approaches to model structural and contact fatigue
Failures caused by structural and contact fatigue of materials are a key issue in modern industry. In order to ensure the safe use of mechanical components, a variety of fatigue modeling approaches have been developed. The first part of this article focuses on the modeling of traditional fatigue; by approaching fatigue problems from a fracture point of view, fatigue life models for crack initiation and propagation are introduced; also, fatigue life modeling based on damage accumulation parameters are presented. The second part of this article reviews contact fatigue modeling approaches; the description of the complex stress state under contact fatigue is given first, followed by a review of plasticity-based material behavior models for contact fatigue; then a number of contact fatigue life modeling approaches are presented and compared; finally, the modeling of microstructural alterations under contact fatigue is introduced. The advantages and limitations of the introduced fatigue models are discussed as well.

Abstract
Failures caused by structural and contact fatigue of materials are a key issue in modern industry. In order to ensure the safe use of mechanical components, a variety of fatigue modeling approaches have been developed. The first part of this article focuses on the modeling of traditional fatigue; by approaching fatigue problems from a fracture point of view, fatigue life models for crack initiation and propagation are introduced; also, fatigue life modeling based on damage accumulation parameters are presented. The second part of this article reviews contact fatigue modeling approaches; the description of the complex stress state under contact fatigue is given first, followed by a review of plasticity-based material behavior models for contact fatigue; then a number of contact fatigue life modeling approaches are presented and compared; finally, the modeling of microstructural alterations under contact fatigue is introduced. The advantages and limitations of the introduced fatigue models are discussed as well.
