SPP1713 - Strong coupling of thermo-chemical and thermo-mechanical states in applied materials
Modeling of strongly coupled magneto-mechanical behavior in magneto-sensitive elastomers
Field-controllable functional polymers represent a relatively new class of applied materials exhibiting a strong coupling of mechanical and external fields. The application of such fields influences the interactions between different local material phases and causes an evolution of the microstructure. A prominent example of such materials which is of particular interest in Project P3 of the DFG Priority Program 1713 are magneto-sensitive elastomers. They feature mechanical moduli that become enhanced under an applied magnetic field as well as the ability for magnetically induced deformations and actuation stresses. This makes magneto-sensitive elastomers very attractive for a variety of technical implementations, especially for actoric applications such as artificial muscles, sensors, micro-robots and micro-pumps. Typically, magneto-sensitive elastomers represent a two-component system, in which micron-sized magnetizable particles are embedded in a soft polymer network. The flexibility of polymer sub-chains between cross-links allows a considerable degree of particle movement and even diffusion under strong magnetic fields. As a result, the particles are prone to organize themselves into chain-like microstructures, which may considerably influence the coupled magneto-mechanical properties of magneto-sensitive elastomers. The goal of this project is the prediction of the macroscopic, coupled magneto-mechanical behavior of magneto-sensitive elastomers. Consequentally, the following tasks arise:
- modeling of the coupled magneto-mechanical behavior of magneto-sensitive elastomers at finite strains
- development of an efficient and robust solution scheme for the numerical simulation of magneto-sensitive elastomers using the finite-element method
- generalization of a magneto-mechanical homogenization framework for finite strains
- prediction of the effective material behavior of magneto-sensitive elastomers based on different idealized und realistic microstructures
- modeling of the microstructural evolution of magneto-sensitive elastomers with a diffuse-interface-model
- comparison of the results with experimental data as well as existing literature
