Crack Geometry

Numerical results are presented for a cracked elastic half-space surface-loaded by Hertzian contact stresses. A horizontal subsurface crack and a surface breaking vertical crack are contained within the half-space. An attempt to correlate crack geometry to fracture is made and possible mechanisms for crack propagation are introduced.

Damage Layer

Ceramic is prone to engender surface/subsurface crack damage layer because of great grinding force and high brittle. Prediction of crack damage of ground ceramic is important for design and assessment of grinding process. In this paper, an investigation for surface/subsurface crack damage of ground ceramic is introduced. Depth of crack damage layer can predicted by calculating crack propagation balance size and a predicting model of crack damage layer depth is obtained.
