## Abstract

Discussed is mechanics of objects with internal degrees of freedom in generally non-Euclidean spaces. Geometric peculiarities of the model are investigated detailly. Discussed are also possible mechanical applications, e.g., in dynamics of structured continua, defect theory and in other fields of mechanics of deformable bodies. Elaborated is a new method of analysis based on non-holonomic frames. We compare our results and methods with those of other authors working in nonlinear dynamics (many of them refer to our papers [20], [21], [49], [50]). Simple examples of completely integerable models are presented.
