Crack growth in an anisotropically rolled thin plate, which contains many i
nitial defects, is investigated by Monte Carlo simulation on a square latti
ce. Each initial defect is assumed to have two crack tips like the Griffith
crack and the effect of anisotropy of a medium on crack growth patterns an
d percolation characteristics is studied. (C) 1999 Elsevier Science B.V. Al
