Abstract
Electroactive polymers (EAP) deform under electric fields and an advantage of

EAP is that they may undergo deformations much larger than those capable by electroactive

ceramics, however at comparatively much lower forces. As common for polymers, EAP exhibit

time-dependent material behavior, i.e. an electro-viscoelastic effect. Modeling of this behavior

is discussed. The forward motion problem follows from the solution of balance of linear momen-

tum and balance equations for the electromagnetic fields, providing the shape and state of the

deformed configuration. In the inverse motion problem the deformed state of an elastic body

for a given set of loads and boundary conditions... (More)

is found by solving the resulting boundary value problem, e.g. with the finite element method (Less)
