Guaranteed lower bounds to effective PDE parameters

Original language description

We are interested in computing guaranteed lower bounds to effective (homogenized) coefficients of heat and elasticity 2D and 3D operators. We compare some approximation spaces to the dual heat problem and show that Lagrange finite elements yield a more efficient method that the usually used Nedelec elements. We show a discretization of the dual solution space of the elasticity equation based on Bogner-Fox-Schmit elements.
