![]() ![]() Furthermore, we reveal that the combination of soft and hard magnetic particles in a hybrid magnetorheological elastomer enables superior healing performance. We demonstrate that the strain at failure is determined by the combined effect of magnetic and adhesive contributions, which are modulated by the applied deformation rate. Moreover, on its healed state, it can sustain higher stresses than the original material without residual magnetisation. The healed material experiences no mechanical degradation during cyclic loading and healing cycles. The results indicate that the proposed soft materials are able to, after several fracture cycles, sustain mechanical loading beyond 20 % strains without compromising the structural integrity. We demonstrate this novel concept with experiments under tensile loading and with a magneto-mechanical constitutive model that explains the healing mechanisms. Then, if new mechanical loading is applied, the composite acts as a continuum structure transmitting internal forces homogeneously until reaching a new failure strain threshold. The north seeking compass needle should point to the north charger pole as the compass is circled around it. Another great buld manual from master builder, Dave Gingery. When the material breaks into two or more parts and these are approached to each other, the magnetic particles with residual magnetisation interact closing the crack. Mount the recharger on a wooden base large enough to also hold a single pole switch and a binding post. This consists of a sticky and soft elastomeric matrix filled with hard-magnetic particles. We propose a new concept of self-healing soft material that does not require external actuation to heal after rupture. ![]()
