Free-energy density functions for nematic elastomers [PDF]
, 2003 The recently proposed neo-classical theory for nematic elastomers is a molecular-statistical generalization of classical Gaussian network theory. The resulting free-energy density predicts the phenomenon of soft elasticity—the ability of elastomers to ...
