Atomic Scaling Processes during Brittle Fracture
Abstract
The goals of this research was to understand the relationship between bond rupture and macroscopic features on the fracture surface and to determine the effect of microstructure on fracture processes. Several important findings were discovered during the course of the project. These findings include the determination that fracture in single crystals on the same fracture plane but stressed in different directions have different toughness values, different fracture morphology and different fractal dimensions, that the characteristic atomic parameter, a sub zero, appears to be equal to the bond distances in fracture, that the profile dimension is not equal to the contour dimension when determining the fracture surface (fractal) dimension and that the fractal dimensional increment is equal to the crack size-to-(mirror-mist) branching boundary ratio (flaw-to-mirror size ratio).
