Effects of Loading Magnitude and Fatigue Crack Growth on Crack Opening-Closing Behavior on Silicon Nitride Ball under Cyclic Compression

Article Preview

Abstract:

To research effects of cyclic loadings and the loading magnitude on the crack opening-closing behavior, crack opening displacement evaluations for fatigue cracks on a silicon nitride ball were carried out. The compressive loading magnitude, which was less than 2.7 kN, did not affect crack opening-closing behavior. The crack opened at the early cycles of fatigue during 0 to 103 cycles.
