: Strain-induced crystallization in natural rubber has long been modeled as an isothermal pro- cess. Recent calorimetric measurements (Samaca Martinez et al. 2013a,b) and a theoretical result (Khi ˆ em and Itskov 2018) revealed severe limitations of this approach. First, it was not able to describe the Gough- Joule effect as well as the rate of crystallization (melting) in natural rubber. Second, the stress-strain hysteresis of natural rubber was improperly attributed to the mechanical dissipation. In this contribution, we present a fully coupled thermo-micromechanical theory of strain-induced crystallization in natural rubber. Accordingly, deformation is accompanied by heat production/absorption. It potentially induces an evolution of the heat source which alters the temperature of the sample. In contrast to previous works on thermo-mechanics of rubber-like materials, the internal energy and the entropy are formulated in our model explicitly in terms of state variables. The crystallinity is not considered as an internal variable, and its evolution is elucidated by crystal nucleation in loading and crystal growth in unloading. The crystallization kinetics (Khi ˆ em and Itskov 2018) is further extended beyond uniaxial deformation, which offers microscopic boundary conditions for the representative chain on the one hand, and provides a formulation for the crystallinity on the other hand. Model predictions are compared with comprehensive experimental results and shed new light on strain- induced crystallization of natural rubber.

The key issue of this contribution is the magneto-mechanical behavior of a magnetically hard magnetorheological elastomer (H-MRE). A numerical model based on the conservation laws of continuum mechanics and magnetism is presented and then applied to a specific 2-dimensional case of an H-MRE specimen. The interaction between two remanently magnetized particles and its dependence on the relative positioning of the particles to one another are studied. The reaction of the elastomer matrix to the particle-particle interaction is analyzed for three configurations of the particles in the specimen. In a second step, the specimen is exposed to a unidirectional tensile load. It is demonstrated that the magnetization of the particles induces a change in the modulus which strongly depends on the arrangement of the particles in the matrix: an increase as well as a decrease of the modulus are observed. By the help of the principal stresses, three different types of magnetic interactions are identified and assigned to the corresponding softening and stiffening reactions of the specimen.
