Shapes of Deterministic Cracks Obtained under Shear
Cracks are grown in a system submitted to external shear by solving the full Lamé equation on a two-dimensional lattice. One finds that deterministic fracture patterns are in general branched and can be fractal. This effect is due to the competition between the direction of global stress and the local growth direction imposed by the lattice anisotropy.
