Dielectric elastomer actuators [PDF]

open access: yes, 2001
Stress and strain are introduced as tensor properties. Several theoretical models of stress-strain behaviour are presented, of which the Ogden model is capable of fitting the observed behaviour in the entire range of measurement. Dielectricity is defined, and Maxwell stress is derived.
