  We investigate linear theories of incompatible micromorphic elasticity,
incompatible microstretch elasticity, incompatible micropolar elasticity and
the incompatible dilatation theory of elasticity (elasticity with voids). The
incompatibility conditions and Bianchi identities are derived and discussed.
The Eshelby stress tensor (static energy momentum) is calculated for such
inhomogeneous media with microstructure. Its divergence gives the driving
forces for dislocations, disclinations, point defects and inhomogeneities which
are called configurational forces.
