Dynamic fracture of disordered viscoelastic solids is studied computationally using the Born-Maxwell model. Two types of disorder have been considered, namely, correlated density disorder and topological disorder. In both cases fracture instability in terms of crack branching occurs. For density disorder dense spots in the system are found to be an effective mechanism of crack arrest. This shows in the length of the daughter cracks and also serves as a mechanism for crack curving. In case of topologically disordered systems we see branch bending. The complicated topology of cracks obeys a scaling law which has been found experimentally.
