Abstract
In the presence of strong adhesion, fibers bundle leading to the formation of a non-crosslinked network of fiber bundles. The structure of these networks is defined by the interplay of adhesion and bending energies. To determine the structure of self-organized networks in the presence of adhesion, the evolution of bundling and junctions between bundles has to be traced in time. To this end, a semi-analytical expression specifying the constraints on the curvature of bundles in the vicinity of a branching point at static equilibrium is derived. Based on this theoretical analysis, a novel computational method is developed to determine the stable configurations of the adhesion stabilized bundle networks and their mechanics by minimization of total energy.
