An optimal scaling law for finite element approximations of a variational problem with non-trivial microstructure
ESAIM: Modélisation mathématique et analyse numérique, Tome 35 (2001) no. 5, pp. 921-934.

In this note we give sharp lower bounds for a non-convex functional when minimised over the space of functions that are piecewise affine on a triangular grid and satisfy an affine boundary condition in the second lamination convex hull of the wells of the functional.
