Experimental and numerical analysis of cord–elastomer composites

Abstract In this paper, experimental and numerical investigations on cord–elastomer composites are presented. A finite-element model is introduced, which was developed within the framework of an industrial project. The able to simulate elastomer matrix with inserted cords as load bearing elements predict strains stresses in cord sections. inelastic material behavior yarns described by corresponding models suitable for large deformation processes. With help a specially demonstrator bellows, similar air spring, simulation results compared experiments. For purpose, digital image correlation method used determine deformations outer surface bellows calculate between cords. comparison shows that employed very well suited these composites.
