This paper deals with multicomponent systems subjected to suddenly applied loads. Such multicomponent systems consist of functionally identical elements, but the elements differ in their ability to sustain the applied load. Specifically, arrays of pillars are an example of the multicomponent systems. The capability of the array to sustain the applied load depends not only on the strength of the pillars but also on how the load coming from failed pillars is redistributed to the intact ones. We employ a Fiber Bundle Model with load transfer restricted within a rectangular region generated dynamically after each pillar's destruction. We investigate strength of the array and its survivability.

Failure process in composite materials is the basis of various actual researches. It study is the almost treated with fiber bundle model (FBM), in the framework of local load sharing rule (LLS), were the breakdown mechanisms is controlled by different parameters. Almost tentative investigates only fiber failure process and neglects the effect of the matrix, as a second crucial component of composite. Effectively, quantification of fibers-matrix interactions is not generally clear. Furthermore, the diversity of composite intrinsic proprieties complicates this quantification. The originality of our investigations is to quantify all interactions between fibers and matrix in a single parameter. Likewise, this latter gives us a different results than the ones obtained with FBM where the interaction amplitude is neglected. Moreover, interaction decelerates the failure process; it subdivides the avalanche phenomena on two consecutive regimes separated by delaying duration. These results are more similar to the ones obtained regular fibers substations. Therefore any fiber have its own elongation, the mean fiber elongation produces an elastic energy. The temporal variation of these latter presents two extremum separated by time duration; at this separated period, the material self-rearranging. These results are more similar to the ones obtained by the regular fibers substitution process.
