  We derive Griffith functionals in the framework of linearized elasticity from
nonlinear and frame indifferent energies in brittle fracture via
Gamma-convergence. The convergence is given in terms of rescaled displacement
fields measuring the distance of deformations from piecewise rigid motions. The
configurations of the limiting model consist of partitions of the material,
corresponding piecewise rigid deformations and displacement fields which are
defined separately on each component of the cracked body. Apart from the
linearized Griffith energy the limiting functional comprises also the
segmentation energy which is necessary to disconnect the parts of the specimen.
