The damage evolution occurring in a set of elements located in the nodes of the supporting two-dimensional grid is analysed within the stochastic approach. The element-strength-thresholds are drawn from a given probability distribution and the elements are treated as fibres within the Fibre Bundle Model. If an element fails, its load has to be transferred to the other intact elements. For different grid geometries we compare the evolution of the number of intact elements under the load with respect to three different load transfer rules: the global, the local and recently introduced so called Voronoi load transfer rule. Our example system is an array of nanopillars.
