RISA Statistical Damage Mechanics Model for Subsurface Initiated Spalling in Rolling Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue lives of rolling element bearings exhibit a wide scatter due to the statistical nature of the rolling contact fatigue failure process. Empirical life models that account for this ...
Evaluation of Stresses Around Inclusions in Hertzian Contacts Using the Discrete Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inclusions are the primary sites for subsurface fatigue crack initiation in bearing contacts. To understand the mechanisms of subsurface crack nucleation under contact loading, a detailed description ...
A Numerical Model for Life Scatter in Rolling Element Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue lives of rolling element bearings exhibit a wide scatter due to the statistical nature of the mechanisms responsible for the bearing failure process. Life models that account for this ...
A Review of Rolling Contact Fatigue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ball and rolling element bearings are perhaps the most widely used components in industrial machinery. They are used to support load and allow relative motion inherent in the mechanism to take ...
EHL Modeling for Nonhomogeneous Materials: The Effect of Material Inclusions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inclusions are common in bearing materials and are a primary site for subsurface fatigue crack initiation in rolling element bearings. This paper presents a new approach for computing the ...
