The magnetoelastic coupling produced by the interaction of an external magnetic field with the ferromagnetic particles dispersed in an elastomer allows to obtain actuators capable of bearing large deformations and with high response speeds. The applications concern microscale devices that can be controlled remotely and used for drug administration, microsurgery and micro/nano fabrication. Their design requires predictive models of slender structures that can be used to optimize the actuator properties.

In this work Jacopo Ciambella of ICI DISG, together with colleagues from RomaTre University and the Czech Academy of Sciences introduced a new mechanical model of a magneto-elastic beam undergoing finite deformations. Instability phenomena induced by the external magnetic field have been studied, and can be exploited to significantly increase the actuation capabilities.
