Abstract

The present chapter investigates the applicability of fractal geometry in fractography. Samples at different times during excavation have been studied to examine fractal characteristics of fracture surfaces. The fractal dimensions of the fracture surfaces were determined by using a vertical section method. Fracture toughness has been obtained by using the three point SENB method. Results show the fracture surfaces to be fractal, but no correlation between the measured quantities has been noticed.
