A mixed finite element method with piecewise linear elements for the biharmonic equation on surfaces
Oded Stein, Eitan Grinspun, Alec Jacobson +1
The biharmonic equation with Dirichlet and Neumann boundary conditions discretized using the mixed finite element method and piecewise linear (with the possible exception of bounda…
Asynchronous Variational Contact Mechanics
Etienne Vouga, David Harmon, Rasmus Tamstorf +1
An asynchronous, variational method for simulating elastica in complex contact and impact scenarios is developed. Asynchronous Variational Integrators (AVIs) are extended to handle…
Asynchronous Variational Integration of Interaction Potentials for Contact Mechanics
Etienne Vouga, David Harmon, Rasmus Tamstorf +1
Asynchronous Variational Integrators (AVIs) have demonstrated long-time good energy behavior. It was previously conjectured that this remarkable property is due to their geometric…
Implicit-Explicit Variational Integration of Highly Oscillatory Problems
Ari Stern, Eitan Grinspun
In this paper, we derive a variational integrator for certain highly oscillatory problems in mechanics. To do this, we take a new approach to the splitting of fast and slow potenti…
