Povzetek: In this work we consider geometrically exact shell model subjected to finite rotations. We present some developments on handling constrained finite rotations that are of direct use in nonlinear static and dynamic finite element analysis of smooth shells. Relationships between different preferred parametrizations of constrained finite rotations are first given in a form of commutative diagrams. Incremental rotation vector for smooth shells is presented as the most suitable parameter for the standard incremental solution strategy as wel as for the construction of the time-stepping schemes. An appropriate consideration is given to construct the corresponding Newmark implicit time stepping schemes for constrained rotations [COBISS.SI-ID 1382241]
