Abstract
Dielectric Elastomers are capable of large deformations in response to
electrical stimuli. Heterogeneous soft dielectrics with proper
microstructures demonstrate much stronger electromechanical coupling
than their homogeneous constituents. In turn, the heterogeneity is an
origin for instability developments leading to drastic change in the
composite microstructure. In this talk, the electromechanical
instabilities are considered. Stability of anisotropic soft dielectrics
is analyzed. Ways to achieve giant deformations and manipulating extreme
material properties are discussed. 1. S. Rudykh and G. deBotton,
