WebThe surface morphology of the fractured surface was studied and analysed. Results: The fracture toughness tests showed that the dental composites grafted with optimum weight per cent (wt. %) concentration of the SCA had a better stress intensity factor (K IC ) when compared to the 2.0 wt. % and 3.0 wt. % concentration. WebIn this paper we explore the possibility of using fractal concepts to describe the complex fracture surface morphology of polystyrene. It was found that such fracture surfaces can be described as scaling fractals (at least over the range of ruler lengths explored here) and that the stress intensity factor at failure increases as fractal dimension increases.
