摘要：

Two statistical models of (strictly two-dimensional) layer destruction are presented. The first is built as a strict percolation model with an added "conservation law" (conservation of mass) as physical constraint. The second allows for damped or limited fracture. Two successive fracture crack thresholds are considered. Percolation (i.e., fracture) probability and cluster distributions are studied by use of numerical simulations. Different fractal dimension, critical exponents for cluster distribution, and universality laws characterize both models.
