Electromechanics of polyurethane elastomers
(2011)- Abstract
- It is well known that electroactive polymers (EAP) deform under electric fields. An advantage of EAP is that it may undergo deformations much larger than those capable by electroactive ceramics, however at comparatively low forces. As common for polymers, EAP exhibit time-dependent material behavior, i.e. an electro-viscoelastic effect. In the modeling the deformation as well as the electric potential are introduced as global degrees of freedom, the internal variables accounting for the viscous response are incorporated at the so-called constitutive level. The proposed model is calibrated against experimental data, and a simple coupled finite element
example is studied to show the applicability of the finite deformation... (More) - It is well known that electroactive polymers (EAP) deform under electric fields.
