Abstract/Artist Statement

Fracture is an old, but unsolved problem where physical processes on the microscopic scale affect the properties on the macroscopic scale. Two important properties affecting brittle fracture are the amount. of disorder in the material and the amplitude of stress waves. We are studying the tensile failure of a brittle glassy carbon foam. We observe that propagating stress waves are one cause of avalanches of bond breaking events just before the final rupture.
