High-Speed Bearing Reliability: Analysis of Tapered Roller Bearing Performance and Cage Fracture Mechanisms

Metals
This investigation examines the fracture mechanisms of 31,311 tapered roller bearing cages using finite element analysis (FEA) and the Gurson–Tvergaard–Needleman (GTN) damage model. Static, dynamic, modal, and harmonic response analyses identify critical

Probabilistic Fracture Mechanics Analysis on the Scatter of Critical CTOD

, 2014
Critical CTOD is widely used as a fracture toughness parameter for structural steels. Critical CTOD often has a scatter of more than one order of magnitude.

Moiré interferometry applied to fracture in titanium tubes [PDF]

, 2007
Despite there being a substantial body of evidence to the contrary, moiré interferometry is often regarded - even by some adherents - as a curiosity of the optics lab.
