A notch methodology to estimate fretting fatigue strength [PDF]
, 2007 The aim of this work is to propose a methodology to estimate the fatigue limit of cylindrical contacts under a partial slip regime. Taylors point stress method, usually applied to estimate fatigue limit for notched structures, was associated with the ...

Fatigue methodology for life predictions for the wheel-rail contact area in large offshore turret bearings [PDF]
Fracture and Structural Integrity, 2016 The present report presents a fatigue life prediction method for large roller bearings applied in the turret turn table for large loading buoy units. The contact points between wheel and rail in these bearings are subjected to a multi-axial fluctuating ...

Computer simulation of fatigue under diametrical compression [PDF]
, 2007 We study the fatigue fracture of disordered materials by means of computer simulations of a discrete element model. We extend a two-dimensional fracture model to capture the microscopic mechanisms relevant for fatigue, and we simulate the diametric ...

Fatigue Limit of Steel with Cracks
Bulletin of JSME, 1975 Fatigue tests were carried out on mild steel plate specimens with various lengths of cracks. The relation between the alternating fatigue limit σw and the crack length was well expressed by following equation. Rp(c)w = αe(sec πσw/2σy - 1 ) = const. where, Rp(c)w is the cyclic plastic zone size at fatigue limit, αe is the equivalent crack length of an ...

Fretting fatigue behaviour of Ni-free high-nitrogen stainless steel in a simulated body fluid
Science and Technology of Advanced Materials, 2013 Fretting fatigue behaviour of Ni-free high-nitrogen steel (HNS) with a yield strength of about 800 MPa, which was prepared by nitrogen gas pressurized electroslag remelting, was studied in air and in phosphate-buffered saline (PBS(-)).
