Nominally brittle cracks in inhomogeneous solids: From microstructural disorder to continuum-level scale

We analyze the intermittent dynamics of cracks in heterogeneous brittle materials and the roughness of the resulting fracture surfaces by investigating theoretically and numerically crack propagation in an elastic solid of spatially-distributed toughness. The crack motion split up into discrete jump...
