Abstract Scope |
The use of quantitative fractography has enhanced forensic analysis of field failures. The combination of fracture mechanics with fractography in glass and ceramic fracture surfaces started mainly at NRL in the 1970’s. Since then, the field has grown to be a viable methodology for failure analysis in fiber optics, dental ceramics, electronic components and many other materials. Fractal geometry was applied to fracture surfaces in metals by Mandelbrot and Passoja and then to ceramics by Mecholsky and Passoja. The application of fractal geometry to fracture surface analysis has enhanced the determination of the cause of failures of both R-curve and non-R-curve ceramics. Examples of the developments in these methodologies lead to exciting possibilities for the future. |
