Dynamic analyiss of multibody systems using constraint elimination methods

In this work, dynamics of simple multibody systems composed of rigid and/or elastic bodies is analysed. The equation of motion for holonomic constrained system are derived by application of standard constraint elimination methods, the penalty function method, the Lagrange multiplier method and the augmented Lagrangian method, above Hamilton's principle. Time integration of equations of motion is performed using the Newmark method without and with numerical dissipation, the Hilber-Hughes-Taylor algorithm and generalized- alfa method.
