Author Affiliations +
This paper reviews state-of-the-art modeling of viscoelastic behavior elastomer (DE) as active material for actuators. First reviewed are the fundamentals of viscoelasticity theory and modeling based on Boltzmann's Superposition Principle, the key operator based on Laplace transform and its inverse Laplace transform, and Correspondence Principle by which solutions of viscoelastic boundary value problems can be determined if the elastic solution is known. Also discussed are the experimental methods of characterizing viscoelastic behavior of DE materials. Finally, viscoelastic constitutive equations are demonstrated to predict the time-dependent bending displacement and blocking force of DE actuators.
