Abstract
Using Contact Dynamic simulations, we study how a rupture length in the adhesive interaction at contact, inducing hysteresis, reflects on the stability of cohesive systems. We examine the combined e↵ect of the adhesive range and the algorithm performances. We observe how long-range adhesive interactions increase the stability of a pile under gravity, compared to short-range adhesive interactions, and compare their increased sensitivity to algorithm precision with the short-range case. The results suggest that long-range adhesive interactions are more prone to propagate local computational imprecisions associated to erroneous displacements, the way some material propagate dislocations, thereby recalling a kind of numerically-induced ductility.
