We study dense, disordered stacks of elastic macroscopic fibers. These stacks often exhibit non-linear elasticity, due to the coupling between the applied stress and the internal distribution of fiber contacts. We propose a theoretical model for the compression modulus of such systems, andillustrate our method by studying the conical shapes frequently observed at the extremities of ropes and other fiber structures.studying the conical shapes frequently observed at theextremities of ropes and other fiber structures.
