Avalanche statistics in transfer load models of evolving damage

The damage evolution occurring in a set of elements in the nodes of the supporting one- and two-dimensional lattices is analysed within the stochastic Fibre Bundle Model approach. The element-strength-thresholds are drawn from a given probability distribution and the set of elements is subjected to an external load that is increased quasi-statically. If an element fails, its load has to be transferred to the other intact elements. We compare avalanche statistics i.e. the number of damaged elements for three different load transfer protocols, namely the global, local and recently introduced so-called Voronoi load transfer rule. Our example system is an array of nanopillars.
