Abstract:

the purpose of this work is to show the correlation between the fractal dimension, d, and mechanical properties such as work of fracture, gwof, and fracture toughness, kic. alumina-mullite-zirconia composites were characterized by the slit-island method, sim, to obtain values of d and its fractional part, d*. the fracture surface roughness was also evaluated using a cyclic voltametric method. it will be shown that there is a positive experimental dependency of gwof on d* and that there is not an evident correlation between kic and d*.
