We study necessary and sufficient conditions for the existence of solutions in SBV0(Ω)SBV_0(\Omega) of a variational problem involving only bulk energy. Related to that we study the problem of finding u∈SBV0(Ω)u \in SBV_0(\Omega) such that ∇u(x)∈E, a.e. in Ω,\nabla u (x)\in E,\text{ a.e. in } \Omega, subject to the condition ∫∇u=ζ0∣Ω∣,\int \nabla u = \zeta_0 |\Omega|, where E⊆RNE\subseteq \mathbb{R}^N is a given set and ζ0∈\zeta_0 \in int co EE is prescribed
