title = "Strength of a C-Sphere flexure specimen",
abstract = "A {"}C-Sphere{"} flexure strength specimen geometry was conceived and developed to measure a relevant strength of bearing-grade Si3N 4 balls and to relate that to surface-located strength-limiting flaws and to ultimately link those flaw populations to rolling contact fatigue performance. A slot was machined into the balls to a set depth to produce the C-sphere geometry. C-sphere specimens were then diametrally compressed to produce a monotonically increasing flexure or hoop tensile stress at their surface that caused their fracture. The strength was determined using the combination of failure load, C-sphere geometry, and FEA, and the stress field was used to determine C-sphere effective areas and effective volumes as a function of Weibull modulus. A description of the specimen and the aforementioned analysis are provided and a comparison of C-sphere flexure strength distributions of two bearing grade Si3N4 materials (NBD200 and SN101C) is given.",
