The report discusses the strain measures for large displacements in both lagrangian and eulerian variables. Similarly, relations are established between lagrangian and eulerian variations of fields with a view to construct eulerian variational principles from the known lagrangian principle of large displacements. Various definitions of stress tensors are also discussed and related. Author
