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 parametrizations of constrained finite rotations are first given in a form of commutative diagram. The incremental rotation vector for smooth shells is presented as the most suitable parameter for the standard incremental solution strategy as well as for the construction of the time-stepping schemes. An appropriate consideration is given to construct the corresponding Newmark implicit time stepping schemes for geometrically exact shells [COBISS.SI-ID 948577]
