Abstract/Artist Statement
The process of brittle fracture is strongly affected by propagating stress waves. In studying the tensile failure of a brittle carbon foam, we observe that by damping out the stress waves, the fracture toughness (resistance of the material to crack growth) increases. This change in a material property leaves behind an altered fracture surface landscape, which can be characterized by a fractal dimension.
