Title: | Mixed finite elements for the equations of linear elasticity with weakly imposed symmetry |
Time: | 3:00-4:00 pm |
Place: | Blocker 628 |
Note: | This seminar will be conducted on Monday |
We exploit the connection between the de Rham sequence and a corresponding exact sequence for elasticity to derive new finite element methods for the approximation of the equations of linear elasticity. These methods use a Lagrange multiplier to weakly impose the symmetry of the stress, thus allowing the use of standard mixed finite elements for scalar second order elliptic problems.
