Summary, in English
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 is specified and the undeformed configuration
is found by solving the resulting boundary value problem, e.g. with the finite element method
