Variationally consistent methods for Lagrangian dynamics in continuum mechanics
… of the equations of motion. Recently, Variational Integrators have been developed where the numerical time integration scheme is developed from a variational principle based on Hamilton's principle of stationary action. Such methods ensure conservation of linear and angular momentum, …

Centimeter-Scale Spacecraft: Design, Fabrication, And Deployment
… algorithm for on-orbit inertia estimation, and variational integrators for spacecraft attitude dynamics that offer improved performance over traditional Runge-Kutta schemes in spacecraft guidance, navigation, and control applications.

Solar radiation pressure, drag and gravitational effects on a dust particle in Earth orbit
… those in lunar orbit. Inclusion of higher-order integrators or variational integrators (over the Runge-Kutta methods used here) may improve accuracy.

Structure-preserving Numerical Methods for Engineering Applications
… is focused on numerical schemes derived from variational principles – schemes that are general enough to apply to a large class of engineering problems. A theoretical framework that encapsulates variational integration for mechanical systems with external forcing and time-dependence and which …

Modeling and Approximation of Nonlinear Dynamics of Flapping Flight
The first and most imperative step when designing a biologically inspired robot is to identify the underlying mechanics of the system or animal of interest. It is most common, perhaps, that this process generates a set of coupled nonlinear ordinary or partial differential equations. For this class …
