Abstrakt EN: The absolute nodal coordinate formulation (ANCF) is a modern finite element based method used in problems of flexible multibody dynamics. It uses the absolute coordinates of nodes and the slopes in nodes as the nodal coordinates. The benchmark problem of a flexible pendulum is used in order to investigate the performance of various time integration methods when using the ANCF. At first, the integration schemes with adaptive time step, which are already implemented in Matlab, are used. Then the classical Runge-Kutta method with the constant time step is implemented and its performance is shown. At last, the Newmark family methods are discussed and their benefits are pointed out.
