Experimental insights into magneto-mechanical rate dependences in MREs

Comprehensive experimental work on magnetorheological elastomers (MREs) just accepted in Composites Part B as part of our European Research Council project 4D-BIOMAP.

We provide more than 600 magneto-mechanical tests on an extremely soft elastomer (~1-20 kPa). The results show material stiffening of ~200 times for axial compression and ~10 times for shear mode. In addition, we conduct novel experiments providing unprecedented magneto-mechanical rate-dependent couplings.

Another relevant outcome is the effect of the structural response versus microstructural features. These lead to specific deformed geometries even with the used of soft-magnetic fillers due to microstructural arrangements and paramagnetic torques.
