Abstract

The paper is concerned with simulation of the damage spread in protective structures with “waiting links.’ These highly nonlinear structures switch their elastic properties whenever the elongation of a link exceeds a critical value; they are stable against dynamic impacts due to their morphology. Waiting link structures are able to spread “partial damage’ through a large region, thereby dissipating the energy of the impact. We simulate various structures with waiting links and compare their characteristics with conventional designs. The figures show the damage propagation in several two-dimensional structures.
