8 Variational Lie Group Formulation of Geometrically Exact Beam Dynamics: Synchronous and Asynchronous Integration
For the elastodynamic simulation of a geometrically exact beam [1], an asynchronous variational integrator (AVI) [2] is derived from a PDE viewpoint. Variational integrators are symplectic and conserve discrete momentum maps and since the presented integrator is derived in the Lie group setting (SO (3) for the representation of rotational degrees of freedom), it intrinsically preserves the grou...
متن کاملMultisymplectic Lie group variational integrator for a geometrically exact beam in R
In this paper we develop, study, and test a Lie group multisymplectic integrator for geometrically exact beams based on the covariant Lagrangian formulation. We exploit the multisymplectic character of the integrator to analyze the energy and momentum map conservations associated to the temporal and spatial discrete evolutions.

متن کاملLie group and Lie algebra variational integrators for flexible beam and plate in R
The purpose of this research project is to develop variational integrators synchronous or asynchronous, which can be used as tools to study complex structures composed of plates and beams subjected to large deformations and stress. We consider the geometrically exact models of beam and plate, whose configuration spaces are Lie groups. These models are suitable for modeling objects subjected to ...
