We present some relaxation and integral representation results for
energy functionals in the setting of structured deformations, with special emphasis given to the case of multi-level structured deformations. In particular,
we present an integral representation result for an abstract class of variational
functionals in this framework via a global method for relaxation and identify,
under quite general assumptions, the corresponding relaxed energy densities
through the study of a related local Dirichlet-type problem.
Some applications to specific relaxation problems are also mentioned, showing
that our global method approach recovers some previously established results.
