  This work establishes a characterization theorem for (generalized) Young
measures generated by symmetric derivatives of functions of bounded deformation
(BD) in the spirit of the classical Kinderlehrer-Pedregal theorem. Our result
places such Young measures in duality with symmetric-quasiconvex functions with
linear growth. The "local" proof strategy combines blow-up arguments with the
singular structure theorem in BD (the analogue of Alberti's rank-one theorem in
BV), which was recently proved by the authors. As an application of our
characterization theorem we show how an atomic part in a BD-Young measure can
be split off in generating sequences.
