Nonholonomic Newmark method
Alexandre Anahory Simões, Sebastián J. Ferraro, Juan Carlos Marrero +1
Using the nonholonomic exponential map, we generalize the well-known family of Newmark methods for nonholonomic systems. We give numerical examples including a test problem where t…
Parallel iterative methods for variational integration applied to navigation problems
Sebastián J. Ferraro, David Martín de Diego, Rodrigo T. Sato Martín de Almagro
Discrete variational methods have shown an excellent performance in numerical simulations of different mechanical systems. In this paper, we introduce an iterative method for discr…
An extension of the Dirac and Gotay-Nester theories of constraints for Dirac dynamical systems
Hernán Cendra, María Etchechoury, Sebastián J. Ferraro
This paper extends the Gotay-Nester and the Dirac theories of constrained systems in order to deal with Dirac dynamical systems in the integrable case. Integrable Dirac dynamical s…
