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

Abstract

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.
