Asynchronous Variational Integrators for Solid Mechanics
Colloquium| Speaker: | Matthew West, California Institute of Technology |
| Location: | 693 Kerr |
| Start time: | Wed, Apr 10 2002, 4:10PM |
Description
Discrete variational mechanics provides a geometric foundation for
understanding symplectic-momentum and multisymplectic-momentum
integrators for mechanical ODEs and PDEs. In this talk we will discuss
the variational multisymplectic formulation of continuum mechanics,
focusing on classical solid mechanics, and show how discretizations of
this can be used to construct spacetime asynchronous
integrators. These methods have a number of appealing theoretical and
practical properties, as will be demonstrated on some simple
elastodynamics problems.
