The purpose of the course is to present a state-of-the-art overview of the continuum theory of both electro- and magneto-sensitive materials capable of large deformations, particularly elastomers and polymers. This will include discussion of the underlying physics and of the mechanical properties of magneto-and electro-sensitive elastomers, nematic elastomers and gels. and computational formulations related to the modelling of these materials from the point of view of material properties and, in particular, control of their mechanical properties will be treated in detail.
The presentations will include carefully crafted overviews of the fundamental formulation of the three-dimensional theory from several points of view. They will also include solutions to boundary-value problems which are amenable to experimental verification, and the numerical implementation of solution strategies that take coupling between field and deformation effects into account. A further aspect of the course will be discussion of stability of equilibria in the presence of electromagnetic coupling together with extensions of the classical energy criterion of elastic stability based on thermodynamical considerations. Additional topics will include extensions of the concept of material, or â€˜configurationalâ€™ forces, the theory of incremental fields and small-amplitude waves, and the consistent derivation of large-deformation models of electro-magneto-elastic membranes and plates.
