Title:Uniaxial nematic elastomers: Constitutive framework and a simple application
Author(s):Chen, Yi-Chao; Fried, Eliot
Abstract:Using a geometrical approach to treat the constraints associated with the continuum description of uniaxial nematic elastomers, we develop the general constitutive framework for such materials. We also provide a variational formulation of equilibrium and use that formulation to discuss the response of a tubular specimen pressurized internally. The analysis demonstrates the existence of a pair of disconnected solution branches. Of these branches, one is stable at low pressure and the other is stable at high pressure. An intemediate regime within which both branches are stable indicates that during loading the specimen may undergo a discontinuous jump from one solution branch to another and thus suggests the possibility of using nematic elastomers for pressure-sensitive optical switches.
