Analysis of Precracking Parameters for Ceramic Single-Edge-Precracked-Beam Specimens

  • Chapter
Fracture Mechanics of Ceramics

Part of the book series: Fracture Mechanics of Ceramics ((FMOC,volume 10))

Abstract

The Single-Edge-Precracked-Beam (SEPB) method involves creation of a straight-through crack from an indentation crack. The straight-through crack is developed by applying a controlled bending load to a specimen via a precracking fixture. The fixture induces a sequence of stable growth of the initial indentation crack, pop-in, and then arrest, thereby forming the straight-through precrack. The effects of indentation load on precracking load as well as on precrack size were studied for experimental variables such as specimen width, precracker span and test material. The finite element method was used to obtain the stress distribution and stress intensity factor, thus providing a quantitative prediction of the experimental results obtained for silicon nitride, alumina, silicon carbide, and two SiC whisker-reinforced silicon nitrides.
