Abstract Experimental investigation of filled rubber reveal several complex properties like hysteresis, permanent set, Mullins‐effect. The connection of these properties to the microstructure is still unclear. The theory of Self‐Organizing Linkage Patterns (SOLP) by Ihlemann is an approach that relies crucially on deviations from average distributions. Specifically, it states that deformed rubber develops a pattern based on physical linkages which is characterized by regions of high and low linkage density. On this basis, all complex material properties can be explained as result of an adaption of the linkage pattern to the applied deformation. The theory is verified by a simulation program which uses a very abstract model of the molecular structure of filled rubber. Furthermore a FEM software is used to mix serial and parallel connection of single SOLP systems.
