RISAnalysis of Vickers Hardness by the Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A particular formulation of the three-dimensional finite element method specifically for analyzing the Vickers hardness test is established. The Vickers hardness of 0.46 percent carbon steel and ...
Propagation of Semi-Elliptical Surface Cracks in Lubricated Rolling/Sliding Elliptical Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the three-dimensional mixed mode stress intensity factors for semi-elliptical inclined cracks formed on elliptical Hertzian contact surfaces are calculated. This analysis accounts for ...

Growth Mechanism of Subsurface Crack Due to Hertzian Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The variations of three-dimensional mixed mode stress intensity factors for a circular crack under a Hertzian contact pressure moving over the surface are calculated by taking into account both ...
Mechanism of Surface Crack Growth in Lubricated Rolling/Sliding Spherical Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A possible mechanism of the crack growth is described by calculating stress intensity factors for a semicircular surface crack under a spherical Hertzian contact moving over a cracked elastic ...
Experimental and Fracture Mechanics Study of the Pit Formation Mechanism Under Repeated Lubricated Rolling-Sliding Contact: Effects of Reversal of Rotation and Change of the Driving Roller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Five rolling contact fatigue tests, Tests {1}–{5} have been conducted. In Tests {1}–{3}, when a fatigue crack was initiated on the surface of a follower, the test was halted. Then, in Test ...
