We discuss the influence of spatially correlated noise on the wandering exponent of the crack-front line during slow in …-plane crack propagation. For a uniform noise, the wandering exponent in the stastically stationary regime is .35±0.02, while the … experiments of slow in-plane crack propagation between two annealed Plexiglas blocks. …

Crack growth in an anisotropically rolled thin plate, which contains many initial defects, is investigated by Monte … Carlo simulation on a square lattice. 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 and percolation characteristics is studied. …
