In this paper we compute all possible null Lagrangians (null energies) for the mechanics of a distinguished class of continua, the nematic elastomers. The computation is done in order to help to relate different physically equivalent theories of nematic elastomers. We discuss both local and global (hence topological) aspects of the problem.

Abstract
In this paper we compute all possible null Lagrangians (null energies) for the mechanics of a distinguished class of continua, the nematic elastomers. The computation is done in order to help to relate different physically equivalent theories of nematic elastomers. We discuss both local and global (hence topological) aspects of the problem.File in questo prodotto:
